ABSTRACT: The cause for the resistance decrease of a solid in a
sur-
face-active medium is the --eduction of sarfa,2e energy un
the border solid-meditim. V'edia which are sim--lar in their
molecular nature decrease The surface ter3ion of "he solid
and rupture takes place, For metals, suzn media are low-
meltirg metals and alloys. Spontaneous diSpersion takes
place along wakened borders, %YhereaG destruztion from out-
side moves along the plane of greatest stress.. The growth
of cracks proceeds with increasing speed unjer outside stress.
in spontaneous dispersion, the speed is mora unifcrm, al-
though low. In Figure 2 the left min-_mum of potentiai ener-
gy corresponds to the stable condition e),f the partic3es in
the body, the right rainimum to The stable condition on the

dium penetrates these micro-:ra--ks qnd anters the interior
of the monocrystal. The decrease ir, resistance in solids
is caused by two facts-. the decrease o-.1' the free surfase
energy, and the two-dimensional pressure of the adsorbed
layer on the steric hindran-~e a-, -the peak of the crack.,
Spontaneous dispersion is possible, if the total stress at
the top of the micro-crack is greater than the safe stress
in the given medium. The safe stress is determined ac~cord-
ing to a given equation by thE surface stress of the body
in the medium.

ABSTRACT: Glass hardening is at present being used in an ever-
-increasing degree as an effective method of increasing
the strength and the thermal durability of glass products,
especially for the production of new types of extremely
solid technical glass. The method of hardening has already
been described previous'ly kreference8 1 and 2). The
elasticity theory- (zeference 1) leads to the following
formula for internal tensions in hardened flat glass:
6 (x) E (F- (1). Finding the mathematical
-form of the function F(x, 1) is the basic problem of the
theory of glass hardening. The tensions of the elongation

Renewed investigation of the influence exercised by
physical properties upon the amount of hardening-tensions
(in the case of regular hardening) showed agreement of
experimental data with the formula (2). The authors
hardened 8 types of glass of different composition. They
were selected in such a manner that there was considerable
difference with respect to the quantity K (table). The
worked-out results (figure 2) of experimental data were
givem in dimensionless parameters'+(~)1~4hawhich m6lm it possible
to compare the hardening formulae with the experiment.
Herefrom it may be seen that not one of the theoretical
dependences agrees with the experiment. This is probably
caused by the fact that the formulae are based upon
inaccurate data. As a result of thn generalization of
Card 2/4 experimental data (figure 2) the dependence of the

hardening function on the criterion of Bio (upper curve)
was obtained. This can be utilized in calculating the
degree of hardness according to formula (2). The analytical
form of this dependence at ha-;,-OP5, which practically
comprises all cases ocarring in the technology of hardening,
can be expressed in the approximation by the formula
Y(S) - 0,23 (f2.
At present degrees of hardness were attained which
correspond to T (J) - 0,31- it follows herefrom
(reference 2) that where the limiting value theoretically
expected at ha ---3t oO is p 0,36, the possibilities
of increasing the degree of hardness are exhausted~

ABSTRACT:
First the formula f,-ir the
oalculation of the strength with

respect to expansion and
bending (1) is deduced. It is shown

that for determining the
strength of the quenched glass

(without destroying it) two
magnitudes must be evaluated;

viz. P - the strength of the
burned glass which is determin-

ed expgrimentallyp and x - a
dimensionless factor which

establishes a relation between the
surface tensions and the

tensions in the middle of the glass
(where the maximum of

expansion occurs). The, authors
investigated the strength of

a flat glass with respect to
cross-bending as well as to a

syiwaotrical bendingr and also
the bending strength of the

rods. The following was fourtd: 1)

of the distribution of Internal stress and the mode of in-
vestigation. 2) The destruction begins at the weakest points.
These are the edges and the surfaceo Depending on the degree
of quenching~ the solidifying of the edges in quenching and
the mode of investigation,the destruction in the one cases
begins at the edges and ih other casesit starts from the sur-
face. In glasses that had not ber quenched the surface
strength is by 300 to 4oo kg/cm higher than the strength
of the edges. In quenched glasses the difference varies de-
pending on the degree of edge solidification) it is, however,
not greater than the above mentioned value- 3) The strength
of the quenched glasses -wary weakly depends on the scale
factor and on the chemioal composition- 4) The evaluation
of the experimental data permits to recommend simple formulae
for the calculation of the strength of quenched glasses.
There are 6 figures and 11 references, 6 of which are Soviet.

ABSTRACT.- Accordint, to the data given by the authors the
characteristics
of friction of a rubber-like and of a solid polymer are dif-
ferent which speaks for a difference in the nature of the
friction of these materials. In the investigation of the mo-
lecular model of the friction the authors start with the model
of the net-like rubber polymer which consists of flexible
linear molecules. The number of the chains in contact with the
surface depends on the factual contact face. Each chain only
temporarily is in contact with the surface and then jumps over
to a new point of contact. The iuthors investigated the fric-
tion of vulcanized rubber on smooth solid surfaces in depend-
ence on temperature, velocity of gliding, load, rubber type,
and the density of the space lattice. The obtained data prove
the characteristic nature of the friction of rubber-like poly-
Card 1/3 mers. In a wide range of velocities (4 orders of
magnitudes)

the experimental dependence is practically described by a
straight line. The sort of the solid support influences the
activation energy. One more diagram illustrates the tempera-
ture dependence of the frictional force of a certain sort of
rubber on steel. According to these data the friction of
rubber-like polymers agrees well with the theorj in a wide
interval of gliding velocities and temperatures. The activa-
tion energy depends, though only weakly, on the structure of
the rubber. The activation energy is weakly, the surface of
factual contact, however, strongly dependent on the modulus
of elasticity of the rubber. On occasion of a transition from
one type of a polymer to an other one the activation enerCy
varies considerably. The external friction (as well as the
internal friction) of the rubber-like polymers is, according
to the obtained data, a molecular-kinetic process which is
connected with the transition of the kinetic units (chains)
through the energy barriers under the influence of the heat
movement and of the external force. There are 3 fi3ures- and
7 references, 3 of which are Soviet.

PERIODICAL: Doklady Akademii nauk SSSR, 1956, Vol. 121, Nr 2,

ABSTRACT: The purpose of the present paper is an investigation
of
the scale effect under different experimental conditions
and with different samples. By scale effect the influence
of the dimensions of the working parts of a sample or a
product on its strength is meant. This effect is most distinctly
marked in brittle material, as e.g. silicate glass. Ex-
perience has shown that the strength of glass practically only
depends on the strength of the surface. At first the authors
briefly discuss a few previous papers (Refs 1-6) which in the
description of the influence of the scale factor on the strength
of glass arrived at contradicting results. In the following
at first the strength of a glass fibre and then different
bending and stretching experiments with glass samples are
discussed. The strength of a fibre only depends on the
Card 1/3 coefficient of expansion a, but not on the diameter of
the

fibre. For a it is valid a - I +F-pi, where 6p, is the value
of the plastic deformation in the production. The crack
resistance does not change by changing the diameter of a fibre
(if a . const). Bending and stretching experiments with glass
plates provided the following results: 1) The strength does
not change with the thickness; 2) Glass, investigated by the
method of vertical stretching, shows an influence of the
thickness on the surface condition: The thicker the glass,
the lower will be the strength of its surface. In figures
the tables show the results of bending and stretching ex-
periments (transverse and symmetrical bending). It becomes
evident that the influence of internal tensions can be neglected
as lonr or these are small. There are 4 figures and 9 refer-
ences, which are Soviet.

ABSTRACT: The paper is a continuation of previous work (Refs
3;6),
inwhich the maximum thermal stress developed on two-sid d
cooling of a glass plate was calculated. This solution
shows that the thermal stress attains a maximum value with
time (SM), and the thermal endurance is defined as

where F, Ii I P I E I h and a are respectively the
ultimate strength, the Poisson's, ratio, the coefficient of
thermal expansion, the Young's modulus, the coefficient of
heat emission and the half-thickneBS Of the glass. The
thermal endurzince of a number of specimens was measured on
cooling in air and in water. The effect of thickness Iof

TITLE: On Testing Strength of Glass
PERIODICAL- Inzhenerno-fizicheskiy zhurnal, 1959, Nr 7, pp 20 -
28 (USSR)
ABSTRACTI: Inorganic.glass Is an ideal material for checking the
theory of elasti-
city. The methods of testing which have been applied so far are,
however,
not very well substantiated, and the data available in
literature are
contradictory. The authors analyzed the tests of flat glass for
trans-
verse and symmetrical bending under statical load$. The checking
of
formulae of the material strength theory for transverse bending
was made
by Frokht, Koker and Faylon CRefs 9,10-7 on glass specimens of
the beam
type. However, according to N.M. Belyayev, when the ratio of
beam thick-
ness to its span d/L-,-' 1/5, it works as a plate, and
calculation condi-
tions should be changed. The authors carried out tests of both
rigid and
elastic glass plates, and the results are compiled in Table 2. A
conclu-
sion drawn from these tests is as follows: formulae applied for
calcula-
ting the strength and the magnitude of arising stresses in tests
for trans-
verse bending, hold for rigid and elastic plates, provided that
deflections
Card 1/3 do not exceed the thickness of the plate. The tests for
symmetric bending

On Testing Strength of Glass

SOV/170-59-7-4/20
were carried out to determine the strength of the surface of
glass
plates. A series of tests with a freely supported plate on a
square
and on a round support, subjected to a load concentrated in the
center,
were performed. For the case of a square plate on a square
support
there are 3 different formulae proposed by Timoshenko ZR-ef 1g,
Roark
,CRef lg and Markus (Ref 157. As can be seen from the results of
tests of a square plate with a square support, presented in
Figure 2,
Markus' formula holds with an accuracy of �10% for the plates in
which
D < 1/6 a, where D is the diameter of the drill core, and a is
the side
of the square support. At D >1/6 a, Roark's formula yields
better
results. For the case of a round plate on a round support, best
results
are yielded by Formula 7,proposed by Timoshenko, provided that
D7 1/4 a.
The authors investigatedmoreoveran effect of the edges in tests
for
symmetrical bending. Their conclusion is that the edges should
extend
by 1 to 2 d beyond the support. The shape of the plate should
correspond
to the contour of the support. In the conclusion the authors
thank S.N.

PERIODICAL: Kolloidnyy zhurnal, 1959, Vol XXI, Nr 1, pp 3-8

ABSTRACT: Ye. V. Kuvshinskiy and Ye. A. Sidorovich ireference 51
developed a method of determining the elastic proper-
ties of rubber during percussion ' and proposed s~theo-
ry of a method which pormits the detemination from
experimental data of two independent constants of
rubber, the dynamic elastic modulus and the angle of
mechanical losses. A pendulum elastometer, described
in detail, was used for the experiment. As a result
of graphic and analytical calculations, the authors
found that at a permanent'initial. percussion speed, a
proportional correlation between the kinetic energy
and the square of the percussion deformation occurs.
The coefficient of this proportionality is called a
Card 1/2 "Percussion modulus". The correlation also holds for

TITLE: The Structure and Structural-1,11echanical Properties of
Inorganic Glasses
PERIODICAL: Kolloidnyy zhurnal, 1959, Vol XXI, Nr 3, pp 249-256
(USSR)
ABSTRACT: The author reports on some experiments intended to de-
termine the 'structuro-mechanical properties of inorganic
glasses. According to the Soviet scientist P.A. Rebin-
der, diffractional methods whioh prove so useful for
the investigation of crystalline matter, are of little
value for the study of disperse phases, high polymers,
organic and inorganic glasses. The study of the struc-
tuml-mechanical properties of inorganic glasses, i.e.
particularly of silicate glasses,-,is, therefore, of
great importance for theascertainment of the struct-
ure of these very complic:ated materials. The author's
experiments have shown that at certain temperatures the

sistent and easily disinteGrates under light loads, but
that it is partially restored after their removal. The
main reason for the solidification of viscous glass,
when cooled, is the process of vitrification. The ag-
gregation process and the thermal history, hoi%,evor,
play an important role in the formation of the glass
structure, which appears in the change of mechanical
behavior of sainples of the same glass sort. The author
maintains that inorganic glasses (massive glasses and
glas.-,, fibers) occupy a position intermediate between
thixotropic colloiL'al systems tind high polymers. This
assumption is based on the behavior of inorganic glas-
ses above the softening temperature and requires 1) the
presence of a temperatu~re region of deformation of the
elastic type, differing from the high elastic deforma-
tions observed below the softenin- temperature, and 2)
the presence of thixotropic properties. The structu-
ration processes above the vitrification tempera-
Card 2/3 ture lead to the formation of a network,

TEXT: The authors demonstrate the passage from the equation
for the
frictional force F given by the theory of rubber friction on
smooth sur.-
faces to empirical equations relating the friction coefficient
to the
load. The reduction of the theoretical equation which is
admissible for
the sliding velocities v>O.lmm/hr shows that the dependence of
F on
temperature and on v comprises three constants (0, S k' U)
that are
determined by the rubber structure. a depends on the rubber
hardness,
especially on the density of the vulcanization network and

nature of the formation of Sf, the actual contact area under

TEXT: The author reports on his attempt of producing thi--k
glass fibers
with the same strength peculiar to thin glass fibers (below
15~k diameter).
Fig. 1 shows one of the most important properties of glass
fibers on the
basis of the author's data: the dependence of tensile
strength on diameter
and length of continuous non-alkaline glass fibers. Fig. 2
shows the
change in strength during pickling with HF. This pickling
eliminates, in
part, the surface faults of fibers, and increases, in part,
the strength,
but without leading to perfect results. The author clarified
the inter-
relations of the individual physical factors which are
responsible for the
strength of glass fibers. He states as follows; glass fibers
have a di-stdn,,,t
anisotropy of the effect of sample size: the fiber length
has an effect
on strength different from that of the diameter. The
physical causes of

this phenomenon are different. The statistical theory of
strength givi',s
no sufficient explanation. But it explans very well the spread
of test
results (Fig. 1 ) , and the dependence of strength on the f i
ber length. The
main physical factor ensuring the high strength of the fiber is
the ir-
reversible viscous deformation attaining some million percent.
No clear
statement can be made at present on the kind of solidifying
mechanism in
connection with the viscous flow. The author assumes that the
strength in-
creases due to a reduction of faults by irreversible viscous
deformation.
These faults become smaller by the I-a-fold (a - degree of
extension - 1+F-;
F, = viscous deformation). This makes the surface faults less
dangerous.
Further, the author assumes that during drawing the solid bonds
(due to
the orientation of chain structures) are oriented along the
fiber axis.
Thus, the material strength increases in the direction of the
fiber axis
with the degree of extension. Though these two factors affect
the glass
solidification during drawing, the author does not know exactly
which nf
the two is more important. He recommends the following measures
to in-
crease the strength of glass fibers: 1) The use of spinnerets
of larger
diameters. At a higher drawing velocity, 15 , 20 p diameter
threads can

becomes much more efficient. 2) The development of a
production and
operation procedure for glass fibers eliminatine the
formation of a
deficient surface layer. The author mentions the Laboratoriya

pp. 238-242
TEXT: After measurements with a pendulum tribometer, the latter author
came to the conclusion that static friction exists in rubber as in
solid bodies (Ref. 10). But later tests showed (Fig. 1) that this method
was not accurate enough to determine static friction in highly elastic
materials. The initial friction is greatly influenced by the duration
of the previous contact between rubber and steel. Therefore, a contact
time of exactly three minutes was maintained in the following experiments
carried out with a tribometer from the Institut rezinovoy promyshlennosti
(Institute of the Rubber Industry). When a tangential force is applied
t6 the sample, it not o-My slides# but an elastic, reversible deformation
also occurs, whose magnitude depends on the thickness of the sample

(Fig- 3). Fig. 2 shows that the results were affected by
the hardness
of the dynamometer. The values are only conditional as
they depend on the
accuracy of measurement of the sliding and on the
velocity of the
tangential force applied. If, however, the rubber sample
is firmly
attached to the base'9the elastic deformation can be
determined, and this
factor can be disregarded in the results (Fig. 4).
Strictly speak'ing,
the rubber undergoes no static friction, but for
practical purposes the
initial friction can conditionally be regarded as static
friction. There

or bending stress. A Table gives the mechanical characteristic values

(Ref, 5)1 the samples were heated before being stressed, in order to
bring about relaxation. Fig. 1 shows the data for the torsion
(torsion
angle !p - f(tOC)); Fig. 2 the data for the bending stress (sag In
relative units as a function of temperature). Fig. 3 shows the
kinetic
deformation curves at various temperatures, and Fig- 4 the arbitrary
deformation of glass during heating. From these experimental data
the
authors arrive at the following conclusions: The mechanical
properties
of inorganic glasses in the temperature range of the anomaly
(between
vitrification- and flow temperature) are different for large and for
small stresses. In the case of a low stress, highly elastic
deformations
occur like in polymers. Herefrom, conclusions are drawn as to a
chaln-
like structure. As the plastic range depending on the steric
structure
is very narrow, glass behavea like a highly viscous liquid under
high
stress (of more than 1 kg/cm2). The glass contains two kinds of
residual
stress; elastic stresses as a consequence of quenching, and "frozen"
highly elastic stresses which manifest themselves by arbitrary
deformation

structure and the
mechanical properties of glass within the range of the anomaly.
In this
range, the glasses exhibit also weak thixotropy. These reversible
processes of structural re-formation have as yet not been
explained. On
the basis of their highly elastic and thioxotropic properties,
the glasses
are similar in their mechanical behavior with polymers, on the
one hand,
and thixotropic colloids, on the other, and therefore have a
complex
structure. According to their composition and pretreatment, both
chain-
like and colloidal structures with distinct mici:oheterogeneity
were
observed. The authors mention papers by P. A. Rebinder (Refs.

samples
were masticated with dibutyl phthalate (DBP), diootyl sebacinate
(DOS),
tricrewyl phosphate (TKP), paraffin oil, or "Renatsit", and
vulcanized
with 2~ of sulfur. Carbon black or chalk was used as a filler.
The
variation of the coefficient k of resistance to frost was
examined at the
five frequencies specified, and from the curves obtained the
authors
determined the temperature T O'l and T0,6 , at which deformation
amounted
to 10 or 60%j of the deformation at 2000, respectively (k - 0~1
or
k - 0,6). As is shown by Fig. 1, deformation in MVPK is a linear
function
of the softener content. Table 1 supplies data of T O'l for DBP,
Table 2
for DOS. Fig. 2 shows the approximately linear function logo -
f('/T).
Thence the authors calculated the value U1, which had been
defined in an
1 0
earlier paper (Ref. 15) and which is a function of the
activation energy.
As is illustrated in Fig. 3, this value drops with rising
softener content.

IheAuthors arrived
at the following conclusions: The effect of plasticizerswis
greater with
polar rubbers than with nonpolar rubbers. The difference
between polar and
nonpolar rubbers becomes manifest in a different action of the
softeners
at high and low deformation frequencies on the intermolecular
structure
and the resistance to frost. When using carbon black or chalk
as a filler,
vitrification shifts toward higher temperatures. The
simultaneous intro-
duction of carbon black and plasticizer lowers the resistance
to frost
with rising carbon black content. The filler increases the
rubber hardness
and, thus, lowers the resistance to frost. A paper by V. A.
Kargin and
G. L. Slonimskiy is mentioned (Ref. 14). There are 7 figures,

TEXT: The authors discuss several methods of determining the

others. .:. .
yield no more than indirect data. Proceeding from a paper by
K. Floyd
(Ref.6), the authors carried out tests on shrinkage as a

temperature and in thin way obtained a simple method of
determining the
compatibility. The latter is based on the condition that two
compatible
components have a single vitrification temperature, wherea's
mixturd'd
from incompatible components have several vitrification
temperatures,
namely, those of their components. A prerequisite of the new
method is
that vitrification.temperaturea be not too close to one
another.
Shrinkage as a function of temperature was reeorded by a

TEXT: The authors made bending tests to study the
influence of duration
and temperature of heating on the strength of glass.
Fig. I shows the
bending strength of glass as a function of heating
temperature in the
range from 500 to 710 OC. Previous tests had shown that
there were no re-
sidual stresses left after a heating time of two hours
and a subsequent
cooling rate of ioc/minute. As may be seen from Fig* 1,
the strength of
glass is dependent not only on the temperature of the
thermal treatment,
but also on the mechanical history of the samples. When
heating over two
hours the bending strength of samples polished at the
edges is almost
doubled. Fig. 2 shows that a heating time of 5 - 6 hours
yields the
best strength factors, regardless of the mechanical
treatment. The

increase, which
attained a maximum of 13.8 in 2-mm glass and a maximum of

The cooling

treatment on the
strength of the glass surface was checked on the same types
of glass., High-
temperature thermal treatment was found to cause no strength

According to experimental and theoretical work (Refs-1-11) thA
longevity of plastics under load is expressed by the approximate
formula: T = Ae - ad' (I)
where 71~' is the longevity at constant stress (r; the constants
A and a depend on the type of material. In the present paper
the longevity of polymethylmethacrylate is investigated under
cyclic conditions, the stress cycle having a saw-tooth form, with
maximum stress cr2, minimum stress (q, and period ID; the

longevity CO at constant stress a0 = 1/2((r, + e2), the longevity
t under cyclic conditions is given by -'-,q.(7). The testing was
carried out in a special apparatus in pure tension at a frequency

ordinate is the logarithm of the longevity in minutes and the

show that the larger deviations of the experimental from the
calculated curves occur at the smaller values or O'l. The
application of Bailey's method for calculating the longevity of
plastics based on the time dependence of strength leads to
disagreement with experimental data in the practically important
region involving a large number of cycles to fracture. For a
small number of cycles to fracture, the calculated and
experimental curves practically coincide.

TECT: A method for the testing of rubber elasticity was developed and the
VWM-3 (UPKM-3) instrument (Fig. 1) des Sned by the KIIRP was applied te this
pur-
pose. It can be used for the simultaneous testing of 8 samples of different
rub-
bers by means of a special attachment designed by D.I. Smirnov and B.S. Tau Y=
Khan. The functioning principle of the attachment is described. Formula (1)
was
derived which can serV6 as the basis for the quick determination of rubber
elasti-
city at low temperature. Two factors, the frost-resistance TO.,l and the
durat!CL
of the forces acting under static deformation, T-, are taken into
consideration.
In developing the method for rubber elasticity testing at low temperatures two
possibilities had to be noted: 1) the testing of newly-processed rubber, 2)
the
testing of mass-produced rubber. The authors refer to the ISO instrument and
the
method recommended by the International Organization of Standards and point
out

that these are applicable only to the second group of mbber. The method
of the
ISO does not include the determination.of the effect of the temporary
oonditions
of deformation on the frost-resistance of the rubber and the inst-rument
does not
ensure the rapid determination of this relationship, since it can handle
only
static load conditions. The UPKM-1 instrument does not have these
disadvantages.
With this instrument the frost-resistance index at dynamic (1,500
bendings/min)
and static conditions can be determined in compression deformations. A
period of
30 see is suggested for the static tests. The design of the UPKM-1
instrument
was Improved (Ref. 3). A mixture of dry ice and alcohol served as the
coolant V/
since an alcohol medium at low temperatures does not affect the results
of the
experiments (Refs. 4 and 5). It was found that the UPKM-3 can replace 8
stand-
ard instruments since it requires less time for the test. A detailed
explanation
is given of the testing method. Using formula (1) the frost-resistance
index can
be calculated. Formulae 2 and 3 represent the frost-resistanee
coefficients for
cases of compression deformation and elastic restoration, respectively.
The lat-
ter factors k and k' are numerically equal to each other, I.e., k k'.

rubber for crystal-
formation which leads to a loss of the elastic properties, Just-
as in the caae of
vitrification. The problems of vitrification and crystallization
in rubber are
further discussed, describing the factors which affect the
crystallization, e.g.,
vulcanization, presence of sulfur, accelerator, amount of the
masticator, stat.,e of
tension of the rubber sample and how the crystallization affects
the density and
hardness of the rubber. The testing method for crystallization
Is explained in
detail. It usually takes from 10 to 30 days, depending on the
rate of the rubber
crystallization. The crystallization Index is taken to be the
provisional period
of crystallization, determining the time which it takes the
rubber to increase its

formation During Vitrification
PERIODICAL: Kauchuk i Rezina 1960, No. 8, pp. 18 - 22
TEXT: A number of investigations were carried out by the authors Into
the
mechanical losses in rubbers with various properties, such as: nitrile
CKH -40
(SKN-40), butadiene -styrene CKC -30 (SKS-30) and methylvinylpyridine
HBnK (M.VPK).
The Aleksandroy-Gayev instrument designed by the NIIRP (Ref. 4) was
used, applying
the hysteresis loop method. It Is known that iA repeated deformations
under -low
temperatures synthetic and natural rubber change over from a
high-elastic sjhRtanR
to a vitrified state (Ref. 1) and this process contrary to the
struoturalizing
vitrification observed in all amorphous substances when cooled (Ref.
2) is desig-
nated here as mechanical vitrification. The frost-resistance which
depends on
this mechanical vitrification and is estimated from the temperature
relationship
of the high-elastio deformations has been carefully investigated in
previous works

(Refs. 1,3,4). However, the changes in the mechanical losses during
vitrification
have not yet been dealt with. It is pointed out that in order to evaluate
the
frost-resistance of any article under conditiqns of repeated deformations
of a
mechanical nature, one must estimate the value of the frost-resistant
coefficient
at which the maximum mechanical losses are observed for various
rubber-like poly-
mers. The latter is also necessary in order to understand the process of
vitrifl-
cation more fully. The method used in the experimental procedure Is
outlined. vl~_
ing the hysteresis loop method the coefficient of the mechanical losses X
was derm-
mined as the ratio of the area Df the hysteresis loop to the area enclosed
within
the load curye and the deformation axis. Figure 2 is a graph of ,he

between the relative hysteresis x, the tangent and the sine of the

between
the inverse temperature 1/rk and the logarithm of the frequency curve of

ed in the measurements. It was seen that the temperature of
vitrification was
higher for samples not subjected to preliminary forces. As the
deformation fre-
quency increases, the vitrification temperature of the
non-subjected samples ap-
proaches that of the samples with a stabilized structure. It
is assumed that the
vitrification temperature drops due to the irreversible break
in the weak, second-
ary bonds during mechanical effeots and due to a decrease in
the intramolecular
action. The measurement data show that for the different
rubbers investigated the
high-elastic deformation is reached at different temperatures.
Therefore the
frost-resistant coefficient K for these rubbers is determined
from Formula 2 K90
as the ratio of the deformation amplitude 60 at a given
temperature to the Ego
amplitude of the established high-elastic deformation E... The
frost-resistant
coefficients for tho investigated rubbers could be determined
by comparing the
temperature relationships of the K and the x values of the
three rubbers which
would correspond to the maximum of mechanical loss. The
Aleksandrov meohanic~al
model with the same relaxation time was used to estimate the
value of the frost-
-resistant coefficient, corresponding to the ma.)Umum of
mechanical loss. It was

PERIODICALi Plasticheskiye massy, 1960, No. 9, pp. 48 - 53
TEXT: The present paper was read at a conference on the strength of
polymers and polymer materials held on May 16 - 18, 1960. The substances
discussed were mainly non-crystalline polymer materials, in particular,
rubber and plastics. The first problem to be discussed was the effect of
temperature on the strength of amorphous polymers during elongation
(Fig.1). The diagram in Fig.1, which is much more complicated than
A. I. Ioffe's scheme for solids, is characteristic both for rubber and
plastics. The main difference between this diagram and the latter scheme
is the introduction of two new temperature ranges between the brittle-
and the plastic region: the forced elastic range (in the region
Tbrittle-T vitrification) and the highly elastic range (between
Tvitrification and Tfusion ). These two ranges are separated by the
Card 1/3

vitrification point which depends on the duration of the
test. The limit af
of forced elasticity is determined from the peak in the
elongation curve
(Fig.2). As is apparent from Figs.2 and 3, the elongation
curves in the
forced-elasticity range and the plasticity range are
similar. A plot of
the experimental data of rubber polymers is presented in
Figs.4 and 5.
These data confirm the scheme shown in Fig.l. It is seen
from this scheme
that a polymer can undergo elastic-, highly-elastic- and
irreversible
deformations (according to deformation rate, temperature
and stress). it
is generally known, specially from publications by N. S.
Zhurkov (Ref.4)
that the strength of all materials is time-dependent
(Figs.6 and 7). The
introduction of a strength limit as material constant is
only justified
in cases where it may be regarded as maximum technical
strength and is
measurable. Simultaneously with investigations on the
strength of
plastics carried jut at the laboratoriya fiziki prochnosti
LFTI
(Laboratory of Physics of Strength of the Leningrad
Physicotechnical
Institute), the time-dependence of the strength of highly
elastic polymel
materials was investigated at the fizicheskaya laboratoriya
NIIRP
(Laboratory of Physics of the Scientific Research Institute
of the Rubber
Industry) and the laboratoriya fiziki polimerov MGPI im. V.

(Laborat'ory of Physics of Polymers of the XGPI imeni V. I.
Lenin). it was
shown (Ref-7) that rubbery polymers, owing to the specific form
of time-
dependence of their strength (Fig.8) constitute a special class
of
polymer. The relation may be written in the form: pd-n, where
-r . time
at which destruction occurs under constant load 6, a
temperature-
dependent and n . a temperature-independent constant. Hard
polymers and
highly-elastic polymers differ not only in the time-dependence
of their
strength, but also in the character of destructiont Plexiglas
(Fig.9) -
CKC-30 (SKS-30) rubber (Fig.10). The questions least-studied
but most
important from the practical point of view are: the working out
of
methods for calculating maximum stress limits basing on data
from single
elongation and data obtained in static tests. Finally the
author points
out the importance of mechanochemistry, which must be taken
into account
in destruction processes of polymer materials, and discusses
the principal
difference between strength and time-dependent fatigue. Mention

TEXT: The authors conducted a study of the packing. ability of ring-
shaped linings with a rectangular cross-section compressed between groove
flanges in sharp pressure drops. The loss of airtightness of these linings
in
the flange grooves takes place by the contact mechanism but, according to
the
authorsl this phenomenon has not been dealt with sufficiently. Comparisons
were also made by studying ring-shapea linings of rectangular oross-seotion
compressed between flat flanges. Tests were made on linings with the
following
dimensionst internal diameter d - 24 mm, external diameter D - 44 mm, height
of lining h - 9 mm. The form factor(D(F) calaulated according to the formula
(D-d)4h was 0-55. The linings were prepared from 4 types of rubbele with the
following compositionss 1)CRE (SKB), carbon black (60 weight parts to 100
weight parts of raw rubber) , captax, sulfur; 2) CK-30 (SKS-30), carbon

represents the relationship of the actual tension to the degree

of the testo& rubbers in static deformation. The tension was
measured every
3 minutes from the moment the given value of compression was
reached, The
obtained measurement data were used to calculate the-static
rubber modulus E
and lining modulus El according to the formula: El - E ( 1
+,(XF) where M =O-5
(Ref, 6). Table 1 gives the values of the moduli of the rubbers
and the linings
and also the rubber hardness according to Shore. The linings
were tested on
a stand at air pressure of 200 atm and 2000. The attachments
containing the
linings were placed into a water bath. The lack of airtightness
was noted by
the appearance of air bubbles. Fig- 3 gives the data on the
effect of the
degree of compression of the linings located between the flat
flanges on the
value of the critical working pressures (i,e,p the pressure
whereby the lining
loses its airtightness). The packing ability of the linings
compressed between
the flat flanges depends on the degree of compression and the
rubber modulus,
If the lining modulus El and the degree of compression S are
known, the speci-
fio compression load can be calculated f. E'S / (1- 6) (Ref.6).

On the Packing Mechanism of Flange Joints Using lhbber Linings
is drawn that the'speoifio compression load of the lining is a
function of the
modulus and degree of compression of the lining and therefore
determines its
packing ability. By changing the hardness of the rubber or the
degree of
compression of the lining the necessary flange tension can be
obtained which
would determine the value of the critical working pressure in
the system of
flat flanges. The critical nature of the loss of airtightness
is explained
by the decreasing dependence of the lining's resistance on the
radial shift.
Since the resilient resistance force of the lining in the
first moment of the
radial shift is equal to zerot therefore the loss of stability
is determined
by the value of the friction force. This explains the reason
for increasing
the friction coefficient in using flange linings. Experimental
findings are
listed to confirm the conclusions drawn and to explain the
effect of certain
factors on the self-packing -phenomenon of rubber lining. The
size of the
clearance between the lining and internal wall of the caliber
was determined
mathematically. Obtained data lead to theae conolusionst 1)
self-paoking
occurs in the presence of any clearance between the lining and
the limiting
ring, but the value of the critical compression F-k depends on
the size of the
clearance. 2) With an increase in the clearance the critical

increases (or the critical specific load of self-paoking f ).
With an increase
in the hardness of the rubber the critical compression loa f k
increases and
at zero clearance the self-paoking takes place at a load fk on
the flanges
which differs from zero and is the higher, the harder the rubber
(Fig 7). It
is stated that for linings between flat flanges under high
pressure one should
apply high-modulus rubbers. For linings in groove flanges the
low-modulus
rubbers should be used, since it is important that the packing
begin at as low
a pressure as possible on the flanges. Summarizing the
experimental results
the authors conclude that the packing of the rubber linings
compressed between
groove flanges (or with a look) at low compressions takes place
according to
the same mechanism as that of the flat flanges (loss of
stability). In high
compressions increasing with the hardness of the rubber,
self-paoking occurs.
The magnitude of the diameter clearance between.the lining and
the wall of the
groove on the side opposite to the pressure has a significant
effect on the
packing ability of the linings located between the groove
flanges. The greater
the clearance, the more the self-packing phenomenon is noted at
high
compressions. For linings located between flat flanges the

TITLE: Strength of Plastics Under Cyclic Loads
PERIODICAL: Plasticheskiye massy, 1960, No. 11, PP- 47-54
TEXT: The present report was delivered at the Conference on the Strength
of Polymers and Polymeric Materials held in Moscow from May 16 to 18,. 1960.
It deals with studies of the strength and durability of some construction
plastics under low-frequency cyclic loads. Tables 1 and 2 give the charac-
teristic physicomechanical properties df the organic glasses and glass
textolites investigated. The following problems were clarified in the in-
vestigation: the durability of plastics under constant and variable loads
Figs. 1-3, 5); effect of temperature on the durability of plastics-
Figs. 2, 4); effect of orientation on the strength of organic glasses
~
in fatigue tests (Tables 2, 3); anisotropy of durability of glass texto-
lite (Figs. 6, 7); effect of asymmetry of cyclic loads on the durability-
of plastics (Fig. 8); effect of overloads and static preloading (Fig. 9,
Table 4);"fatiguell of the material under cyclic loads (Fig. 10). It was

found that the relationship between durability and stress in
semilogarith-
mic coordinates was not linear under cyclic tensile loads in contrast
to
static loads. In the range of high stresses, the material is longer
durable
under syclic than under static loads on the same stress level. On low
stress levels, however, longer durability of the material corresponds
to
static loading. Under cyclic loads, the same durability of plastics
can
be attained with different values of average cyclic stresses. Here,
longer
stress amplitudes correspond to smaller average cyclic stresses. It
was
shown that an overload during cyclic loading or after prolonged static
loading reduced the durability of the material. Plastics of the
series of
organic polymethyl methacrylate glasses of linear structure with
increased
heat resistance also show a higher fatigue strength both at normal and
increased temperature. Organic glasses with oriented structure, which
were
subjected to biaxial tensile loads on heating above the vitrification
temperature, have a considerably higher fatigue strength than
non-oriented
glasses. Besides, the relative difference between the values of
durability
during fatigue tests, especially with not too high stresses, is much
smal-
ler fn oriented than in non-oriented glasses. Anisotropy of mechanical
properties of glass textolites also occurs in fatigue tests. The
durability
of glass textolite is more strongly reduced by thermal aging under
simul-

taneous cyclicloads than without such loads. Finally, it was shown
that it
was possible to calculate the durability of plastics, especially
organic
glasses, under cyclic loads according to fatigue test data under
static
load with the use of the "criterion of total damages". It was found
that
the fatigue strength calculated did not agree with experimental-data
in
the case of small stresses. The authors attempted to find the causes
of
such disagreement (Fig. 11). They showed that the heating of the whole
sample due to hysteresis losses cannot be the principal cause. Local
overheating is assumed. M. M. Gudimov and B. V. Petrov are mentioned.
There are 11 figures, 4 tables, and 13 references: 11 Soviet and 2 US.
