scientist mentioned in the title. Shevandin was one of the
leading scientists in the field of material mechani-.s; he
became famous for his investigations of the nature of
destruction by brittleness and the phenomena of destruntion
by brittleness of metals at low temperatures carried out at
the Fiziko-tekhnicheskiy institut (Physical and Technical
Institute). After 1945 the deceased dealt with the problems
of cold-shortness of ferrous metals which are of great im-
portance in ship-building. Ye. M. Shevandin published two

TEXT: Complete diagrams plotted by the strip and-the plate methods, are
-iven for the residual stresses in glasses of 1,5, 3, 5, 8, and 12 mm

Boguslavakiy (DAIT SSSR, 129, no. 6, 1362, 1959; author's certificate.
132374, 1959). Mechanical measurements of residual stresses clearly
proved the advantages of glass quenching in liquids, indicating that this
method of quenching oughtto be further developed. Thin glasses poorly
quenched in air blasts have the same quenching stresses, after a second
liquid quenching, as thick glasses after a quenching of 3-4 Por./cm.
Considerably higher compressive stresses occur on the surface of thick
liquid-quenched glasses. They are higher than when the glasses are
quenched in air blasts for the same period. Since under these conditions
the optical stress measurement is not reliable it should be replaced by

a mechanical measurement of the residual stress. Quenching causes higher
stresses in square glass plates than in prismatic glass strips. The
stresses in quenched glasses can be better determined by mechanically
measuring the residual stresses in plates (biaxial st;te of stress) than
by the customary method using specimens in the form of strip. There are

TITLE; Glass hardening
PERIODICAL: Fizika tverdogo tela, v- 4, no. 8, 1962, 2160-2i6a
TEXT: Glasses were tested after being hardened in the following ways:
(1) by quenching in polysiloxane liWaids and in mineral oils; (2) by
etching in hydrofluoric solutions, and (3) by quenching with subsequent
etching.- In each case the specimens were of vertically drawn glass,
measuring 80 mm square and of 1-5, ~.Oj and 590 md thickness I with both
natural.and mechanically polished surfaces. The strength of,the GlaS3
plates 1-5 to 3-0 mm thick was found to be only allghtly increased by
quenching in air blasts. The strength of those 5 to 6 mm thick can be
increased, by quenching in organosilicon oils or in mineral oils, from
10-20 kg/mm2 up to 30-80 kg/mm2. By subsequent etching in hydrofluoric
solutions it can be to 60 to 125 kg/mm2. By this method of hardening the
strength of the glass plates 1.~-3-0 mm thick could b.e increased 'too the
anprecedented level of 50 kg/mm . Glass hardening by quenching in air

blasts and liquids is due to compressive stresRes generated in the surface
and largely to physical changes produced in the surface layer of the
glass. The contribution of these physical changes to hardenin.g. is the
greater the more rapidly the gas is cooled. This two-stage hard'ening
process is well suited for'the commercial production of large glaszes and
for various engineering purposes. There are 3 figures and I table.

TITLE: A problem of the collision of plastic bodies

The collision of a plastic' solid of- revolution (2) with a plastic
senispace ~1) is studied on the assumption that the axis and the velocity
vector of (2) coincide with the surface normal to the semispace. The
problem is solved in terms of the theory of dimensions (L. I. Sedov,
Metody podobiya i razmernosti v mekhanike - .1-lethod3of.similitude and
dimensions in mechanics, M., 1957). The parameters of the shock adiabate
are used to allow for the compressibility of the two bodies$ a IineaK
relation beinG assumed to exist between the velocity D of the shock wave
and the mass velocity u behind the wave front. The pressure behind the
wave front is then p - 90 Du - %(a + Ivu)uj where.a and b are constants of
the material, determined from the shock adiabate, and qo is the density at
standard pressure. The process is described by the impact velocity v 0, the

were explained the wave amplitude changes after the first collision, reflection from
the ends of the second collision during which the structure of the tensile impulses

'the sample and recording of parameters of the waves,along the rod make it possible
to measure the strength of materials which approach a brittle state. The method

ABSTRACT: A direct measurement was made of residual stresses in
glasses with a wide range of thickness, quencbed at different cool-
ing rates, in order to compare the resultant data with the theory
in the range of Biot numbers hitherto uninvestigated (Bi > 5). This
research was set up as a check on the hitherto prevalent opinion
that quenching stresses cannot contribute much to further strengthen-
ing of glass. Glass plates 160 mm square and 5-25 mm thid1r. were

quenched in two liquids having different cooling abilities. The
.fact that 25 mm plates quenched in liquid could lead to heretofore
unattainable compression stresses on the order of 50 kg/MM2 (double.
what can be accomplished with intense air quenching) indicates that
.the possibility of increasing quenching stresses have not yet been
,exhausted. The seeming discrepancy between the intense growth of
,compression stress and simultaneous str6ng attenuation of the tensile
,stresses is explained. 'Comparison of the experimental data with
:several theories of glass quenching shows that the theoretical cal-
.culations of V. L. Indenbom (Collection: Fizika tverdogo tela, 1,
.Izd. AN SSSR, 1959, page 236) are in better agreement with the test
.results than those of G. M. Bartenev (Mekhanicheskiye svoystva i -
teplovaya obrabotka stekla, 196'0). The final conclusion is that one
of the promising ways of-strengthening thick glass still lies in
the possibility of increasing the Biot number during their quenching
and in the appropriate development of suitable quenching media.

ABSTRACT: The tec~mical tensile and bending strength of glass Is known to be much lower
than theoretical (e.g. for sheet glass the strength is -10 kg/mm2 whereas theory predicts
a strength of -1000 kg/mm2). In this connection, the author presents certain results of a new

ABSTRACT: It has been shown elsewhere that the strength of bulk sheet glass after etching in
hydrofluoric acid solutions may be unusually high if the working surface of the glass is thoroug
ly protected from accumulations of defects before and during the experiment. The present
investigation attempts to extend this finding to commercial bulk quartz glass and to study the
influence of the temperature and the heat treatment on the strength of the quartz in its high-
strength state (about 300 kg/mm2). It Is found that if the action of the irreversible heat proc-
essos wh1ch softens the glass and the Influence of moisture in various manifestations are ex-
cluded, the strength of the quartz glass In the 50--400C temperature range Is independent of

TOPIC TAGSt sheet glass, high strength glass
ABSTRACT: It is shown that the values given in the literature for the strength of
plate glass etched in hydrofluoric acid solutions are sinderestimated because insuffi-
cient attention is paid to possible accidental damage to the glass surface which may
take place both before testing and while the glass is in the test installation. To
verify this facto special precautions are taken in 'testing the strength of glass af-
ter etching to see that damage to the surface is scrupulously avoided. A comparison
with control experiments shows that the level of strength and dispersion in values ob-
served in earlier experiments were due mom to side factors than to the properties
of the etched glass. The experimental data show that the guaranteed minimum values
for the strength of the etched glass may be more than 100 kg.mm 2. When precautions
are taken to avoid handling of the glass in any way after etching, ordinary window

glass shows an average bending strength of 1,250 kg*mm 2 with a much narrower spread ii
experimental values than previously observed. Measurements made in a dry vacuum to
eliminate the effect of ambient humidity showed a more than double increase in
strength. The experimental observations show that high strength is a property in-
herent in amorphous solids. It is suggested that the problem of producing tj&h.-
strength glass 4W,/be solved not so much by developing methods for strengthening glas,
as by seeking ways to protect it from being weakened, since it is already in a super-
strong state in its natural form. Orig. art. has: I figure, 1 table.

ABSTRACT: Measurements of the strength of various parts of window glass before and after
etching with hydrofluoric acid showed a great scatter of values (10-160 kg/mm2 for etched
glass). Measurements made after steps were taken to protect the etched surface from new
flaws show that glassses reinforced by etching, i. e, freed from inherent and acquired sur-
face defects, manifest their actual high-strength state if no accumulation of random damage
is allowed to occur prior to and during the test. The observations lead to the important
conclusion that the structural state of massive glass is in no way stronger than the state of
glass fibers or drawn rods. Orig. art. has: 1 figure.

TOPIC TAGS: glass property, high strength glass, hardening
ABSTRACT: The authors examine the reasons for the spread in individual strength_
values for glass hardened by various thermal and chemical methods. It is assumed
that the high strength observed in certain specimens from a single batch of glass
~is not an accident, and that this high strength would show up in the majority O:up-i
Ithe glass specimens if it were not for strong suppressing side factors. These
ipressing effects are attributed chiefly to atmospheric humidity and to possible
Jdamage of the glass during installation in the testing equipment. To test this hy_~
,pothesis, experiments are conducted in which the glass is protected from harmful
1factors from the moment hardening is started. St-nength measurements show that
~these precautions raised the minimum strength level noticeably in the scatter zone.:
!However, it was found that weakening influences were not completely eliminated.

Samples were then selected which were free from visible surface defects. This pre-.~
caution further narrowed the scatter region and consequently increased the average
i
Istrength of the batch of glass samples tested. Similar tests conducted with vari-
I
Lous types of glass hardened by various methods show analogous results. These ex-
;periments indicate that super-high-strength glass can be produced by finding practi-
,cal ways to eliminate the weakening factors. It is recommended that further re-
:search should be done to deternine jnst what these harmful factors are. Orig. art.,

the fundamental principles for calculating the atoniization process
in Injectors. Also, new data on the combustion of droplets of
heavy liquid fuel are given which make It necessaryito reconsider
th6 accepted concept that vaporization of a liquid fuel always

in the design of such furnaces. The second part of the collection
presents data necessary for the calculation of the emission of fly
ash whereby it is shown that this emission is of great significance.
~In addition, the character of furnace temperature fields'is ana-
lyzed. The articles of the third part present the fundamental laws
of gas flow through a layer of fuel and give the theoretical
principles necessary for,calculating the aerodynamic resistance
of the layer-and the speed Of drying in it. The data given in the
collection accurately define current ideas regarding the charac-
teristics of development of a number of phenomena which form the
