Representation of the Approximating Function. A
Laplace transformed functlon must be derived expressing
the exponential polynomial used to approximate the
temporary characteristic Df the system. Let the
temporary characteristic be approximated by an exponential
polynomial at 2n equidistant nodes of Interpolation.
Then function (7) may be round. By means of this
function an arbitrary number of equidistant values
of the n-th order exponential polynomial may be
determined. To this purpDse this function may be ex-
panded Into a series of negative m-orders, or else
the recurrent equation (8) may be applied. The re-
lationship between symbols A and a is found., where a
are coefficients of the ciaracterietit equation (4).

An example Illustrating tae proposed method Is given.
In conclusion, the author says that: (1) A method Is
given of calculating the transient states by means of
recurrent equations obtained uslng the approximate ex-
pressions for the operator of differentiation and the
method of doubling the pitch of discrete values. The
method gives a high degree of accuracy. (2) The method
Is given of obtaining Laplace transformed functions
corresponding to exponential polynomials which Inter-
polate the given temporar7 characteristics at equidistant
nodes. This method may be used for graphically given
functions. There are 4 references, 2 Soviet, 2 U.S,

tABSTRACT: An approximate method Is proposed for determining the loads acting on the
,bottom plates of a vessel during launching from a longitudinal slip. The procedure
,Is convenient from the computational standpoint and.conaLderation is given within cer-.
tain limits to structural flexure of the ship and to various other factors Involving
reactions of the launching ways In the second period. The ",actions between the slLd-1
.ing and ground ways in the second period of the launching operation an given tW the

Ubere s Is the distance from the cross section of the ship passing over the throshol4
lof the launching vays to the cross section being considered, r(s) is the intensity of
the reactions in the launching wsys during the second period of the W, bins opera-
~Ion, ro(x) Is the intensity of rewtAcus, in the launching vays after the vessel has
ibeen transferred from the building w4yi to the launching ways, r(P, M, 2) Is the in-
tensity of the reactions in the launching ways due to the concentrated force P and
the concentrated moment N in the cross section of the ship passing over the threshold
of the launching vays. Accuracy In determination of r(s) by this formula depends
l
lbasically on the degree of accuracy in determination of reactions ro(s) after transfer
of the vessel to the launching vars. Uperinental data on ro(s) for six ships vith
launch veights from 1500 to 4500 tons and lengths free 85 to 140 meters show that the
actual distribution of these reactions differs considerably from the theoretical dis-
tribution based on representation of the vessel during launching as a girder on ar.
elastic base under the effect of the launching load. Contrary to theoretical predic-
tions, no significant reaction pes1w were observed in W of the six experimental
leases considered. Reactions of the launching vays after transfer may be considered

~ABSTRACT: The authors consider the problem of the strength of bottom plates during
launching of ships from a longitudinal slip on ground ways with discontinuous wooden
sliding ways. Expressions are derived for determining the compressive stresses in the

,sliding ways resulting In stresses equal to the yield stress of the material for the
I
.bottom plates. It to shown that compressive stresses or 10-12 kg/c&2, which are
.average for sliding ways made from boons with a cross section of 25x25 ca, produce no
plastic deformations in plates vith a yield stress of 4000 kg/cm2 and a thickness
.greater than .10-12 mm. However, thin plates my be subject to plastic deformations

~fer of the ship from the building vap to the launching ways as well " in the second

PERIODICAL: Inthenerno-fizicheakly zhurnal, 1959, Nr 7, pp 45 - 52 (U33H)
ABSTRAM The authors studied regularities In the fracture of Pure and alloyed
single crystals of zinc along the cleavage plane (0001). Pure crystals
were taken of 3 kinds: containing 99.999% of elemental zinc, containing
99.99% of it and commercial zinci those of alloyed specimens contained
0.2 and 0.5% of cadmium. Experiments were carried out in two versionst
in the absence of an active absorption medium at a temperature of -1960c
and with a thin mercury film of about 5A,.thick applied to the specimen,
at room temperature. Crystals were produced by the zonal crystalliza-
tion method and were 0.54 to 0.9 mm in diameter and about 10 mm long.
The fracture of crystals was performed on the Polyany device at a con-
stant stretching rate of 10 to 15% per minute. The authors formulated a
"condition of the constancy of the product of nomal by shearing stresses",
which is expressed by Formula 1. pc Tc' - const . K2. By &n&lyzing &

this condition is fulfilled within a wide range or orientations or
single crystals for both pure and alloyed specimens. As the quantity
of the admixture increases, the value of X also increases. The authors
explain this by'& hypothesis an th* origination of heterogeneities In
the shearing process and oacurreaos of plastic deforwation during a

ABSTRACTs Single crystals of mine (99,99%) and cadmium (99,99%)
were used in fused tin and lead. Samples were deformed
at 18-13% per minute with a temperature constant to

on the sample electrolytically (thickness 5 p)# which
was then placed in a tube with powdered graphite to
prevent oxidation, Figure 1 shows true stress-strain

The effect of pur* lead I* very slight but with increase
of tin content in the lead up to 20%, there is a sharp
decrease in strength and plasticity of zinc (Figure 3).
With further Increase or tin content, the affect is much
slighter. It was ehgwn that it zinc coated with tin is
held in lead at 400 C for long priods, the strength of
the zinc recovers (Figure 4). This shows the absence of
any marked diffusion of tin in zinc. A decrease in
plasticity and strength of cadmium in tin was also found
~(Figures 5$6). The results on single crystals show that
the decrease in strength is not connected with any grain-
boundary effect.

TEXTs In the introduction, the authors refer to some of their own
previous papers (Refs. 1 and 2). There, it had boon clearly established
that in the rupture of amalgamated single zinc crystals a spread of
rupture stresses occurs along the basic plans (0001). If, for a given
angle Xo between the plans (0001) and the sample axis, P.,,(Zo) and

TITLE: Mechanism of coarse destruction of metallic crystals
PERIODICAL: Yisiks, tyardogo tols, Y. 3p no. 3, 1961, 902-910
TEXT: Studios conducted by the authors in their laboratory hay* shown that
the mechanical proportion of metals can be strongly Influenced by placing
them in highly adsorbing media (fusion of fusible metals). such a treatment
results in a considerable decrease in plasticity and strength. In the
papers of Academician P. A. Robinder at &I. on the affect produced by advorp...
%ion from the ambient sodium upon the moobantoal properties of solids, thosi Ix
effects have been ascribed to the considerable decrease in free surface
energy on the boundary between the deformed metal and its saturated solution
in the other liquid metal. This effect of the metal melt occurs immediately.
Experiments have shown that the rule governing -the deformation and coarse
destruction of metals is not altered by the presence of the liquid n*tal.
The study of the mechanism of coarse destruction of metals in, however,
considerably facilitated by the use of active metal molts. The present

pap*r includes a detailed discussion of experimental data relating to this
subject. The data were obtained at room temperature for amalgamated single
crystals of zinc. Theoretical investigations have shown that the destruc-
tion (rupture on elongation) of single crystals of metals can be divided
into two stages; Stage A: More or lose slow formation and extension of
"embryonic" cracks at points of elevated concentration of strossoo. causod
by inhoaogen9ities of plastic deformation. In this stage, the shear stress
i plays the most significant roloo Tho.growth of the cracks to accompanied
by the occurrence of now dislocations. Stage B: Rapid extension of an
unbalanced crack over the entire cross section of the crystal. This process
in predominated by the normal stress p. The critical relation between nor-
mal stress and shear stress is given by p 010 a 7 2Gd/L, where y is a dimen-
sionless coefficient which differs only slightly from 11 0 Is the shear

coefficient of the order of unity. The two last-mentioned relations which
characterize A and B# respectively# are experimentally verified independent-
ly of each other. This was done by,:,study of the formation of cracks on
an increase in P9;nd i. The speoin (amalgamated single crystals of zinc)
had a purity of 99~1 a diameter of 1 mat a length of 10 am, and showed
different angles of inclination of the basal planes toward the axis of the
specimens. The rate of elongation was constant and amounted to 12%/mln.
The stresses were determined from the relations
To a PosinX0cos~, Po - Posinl(cslnX, where P.0 Is the tonsil* stress referred
to the initial cross section, and X is the angle of inclination of the basal
plans toward the axis of the spoolmonfor a given deformation E. The valid-
ity of the function amax(t) was proved by a series of specimens with
X;1 a 210p and specimens with Xo varying from 16 to 670 showed the correct-
ness of the relation (2) by Griffith. A study of cracks of destroyed
!,,!Pecimens has shown that the predominant role in the formation of destruc-
,ve cracks is presumably played by angular or screw dislocations.

HIT: The authors studied the offset of polyvi nyl alcohol on the r*- w/
duetion of Cu-, Cd-, and Za tons on a dropping mercury electrode from A
chloride ammonium solution. The investigation of the applicability of
polyvinyl alcohol for this purpose was suggested by Professor A.A. Tag*rj
who in thanked by the authors. The studies were conducted on a visual
polarograph of the YIAH(UPAN) system* The amperage was measured with a
reflecting galvanometer of the typo M-21 (M-21). The potential of the
mercury electrode was measured by the compensating a*thod referred to a
saturated colonel electrode. This calomel electrode, which was oonnoot-
ed with the sleatrolyter by a low-resistamoo electrolytic bridge, served
as anode. The mercury vat previously distilled in vaouo. All solutions

from the doubly distilled water. After previous avelling in a small
amount of water, the polyvinyl alcohol(mcilooular weight 25,000) was dis-
solved. The cations were polarographed ov a ehloride-assonium background

aUlf1te in 100 ml of4solution. The ammonia -was distilled In a glass ap-
paratus. Ammonium chloride and sodium sulfite were recrystallized from
doubly distilled water. Figs. 1-3 show the results. The upper curve
(Fig.1) has two maxima whose character has not yet been determined. Poly-
vinyl alcohol suppresses current maxima on all curves studied. A table
.shows that, In the presence of polyvinyl alcohol, the reduction of oop-
