detonation of a charge placed directly on the frog-point or by impact
of a plate activ t d b an explosion. in both methods the frog-point
had to be coate4w:th I layer of clay to prevent the formation of smal'

TEXT: The author analyzes the propagation of oscillations in a system con-
sisting of elements of different mass with linear forces acting between the ele,
inents, when the wave length considerably exceeds the dimensions of non-homogene-
ities. A formula was obtained for the phase velocity without and with taking in-
to account decay (due to viscous friction). In heterogeneous media decay in-
creases abruptly on account of friction. A case is considered when different
elastic forces are acting between the elements; this corresponds to the perio-
dic alternation of layers with different properties. It is noted that the pro-
pagation velocity in a heterogeneous medium may be lesser than that in a homo-
geneous medium. This type of phenomenon is, in the author's opinion, connected
with the relative shift resonance of two adjacent elements. I. Khaykovich

TOPIC TAGS: HF*k~,,free oscillation, seismic wavelp-pogeti-s, wave equation
ABSTRACT: The mechanisms of seismic wave separation by high frequency filters were
studied. The important parameters affecting seismic impulses and filtration were
examined in order to determine the resolving capability of high frequency seismographs
and establish optimum conditions for their use. A theoretical analysis is given for
determining the resolution capability of high frequency filters, applicable to output
signals of spectra wbich can be represented by algebraic functions. It was shown that
oscillations registered on high frequency output filters had a superpositioned fre-
quency for forced oscillations close to the frequency of the input signal, while the
high frequency free oscillations of the filter weve close to the actual frequency of
the process. All high frequency oscillations started at the time when the higher de-
rivatives from the input signal underwent disruption; In this way the separations and

correlations of the high frequency waves were deduced from the separation and correla-
tions of the signal disruptions. The lower the number of derivatives above which all
of the higher derivatives began to undergo disruption, the greater was the absolute
magnitude of the free oscillations and the more the free oscillations prevailed over
~the forced'ones. By increasing the natural frequency of the filter the intensity of
Ithe free oscillations and of the registered high frequency wave decreased. The charp-
~est input signals always resulted in greatest clarity and intensity of the output sig-
nal. The uscful range of filter operation was determined and this was related to R(w)=-
frequency characteristic of the filter, w--rotational frequency. Orig. art. has: 9

ABSTRACT- In order to evaluate the effect of technological factors of smelting
and casting on the susceptibility of Cr-Ni-Mo steel 34KhNZM to
cleavage fracture (CF), six forgings made of this steel (five of which
exhibited GF) were investigated. The investigations dealt with the
following factors: Macro and microstructure, the nature of the frac-
ture, i'lcidence of nonmetallic inclusions, and the mechanical proper-
ties of the forgings. It was established that CF is observed only in
the upper and central portions of the forgings and that it is'independ-
ent bf.the concentration of nonmetallic inclusions and gases in the
steel. CF is caused by a coarse dendritic structure which had
formed as a result of excessively high casting temperatures and

ABSTRACT: Investigations of long duration failures of austenitic
pipes under the effect of internal pressure were carried out on
tube specimens. The tubular and also non-hollow cylindrical
specimens, intended for-uni-axial tensile tests specimens, were
.produced from the sauie original rods of IX18H9T steel. The
material for all the specimens was first subject to 4-at treat-
ment in two batches, consisting of heating to 1 120 C and
cooling in air, folloi,,ed by stabilisation at 80D for 10 hours.
The heat treatment of one batch (A) was effected exactly accord-
i.ng to specifications whilst for the second batch (B) this was
hardened at a slightly reduced temperature. This was done
because similar cases can easily occur in heat treatment uader
shop conditions and, therefore, the test carried out on batch
B isconsidered of great practical.,inter8st. The test results
obtained at 650, 700 and partly at,600 C on tubes of the heat
treatment batches A and B are given respectively in Tables 1

ABSTRACT: The problem of plastic flow of a tube at finite
deformations has been dealt with by a number of authors
(Refs.1-4). In this paper an attempt is made to determine
the time until fracture on the basis of the analysis of
the creep of tubes at finite deformations. The creep
speed at finite deformations is determined according to the
Hoff formula (Ref-7) Eq.(14); test results carried out by
the author on the steels 20, 12MX4~ and 1X18H9T are in
agreement with this formula. A formula for calculatinfr
the time until rupture is derived and the results are
compared with experimentally determined results in the
graphs Figs.1-3. On the whole, the agreement between
experimental and calculated results is satisfactory. The
described solution characterises adequately the qualitative
picture of fracture and is also suitable for a rough
Card 1/2 quantitative evaluation. The difference between the

experimentally and theoretically determined times are
approximately of the same order of magnitude as in the
case of uniaxial tension; the slight divergence between
experimental and theoretical data in the case of uniaxial
tension is confirmed by the data of Hoff who evaluated
the experimental results of Dorn and Tietz (Ref.11). The
here considered rupture scheme during creep is based on
the conception of continuous flow of the material of the
tube maintaining fully the initial geometrical shape
riSht up to the instant of fracture.

ABSTRACT: The results of various authors, for instance, of
Neal, B. (Ref-5) relating to the determination of the
torsion resistance of an initially bent rod prove
indirectly the usefulness of the plastic flow theory.
Therefore, the authors considered it of interest4o
accumulate various experimental datEL on this problem and
here results are described of torsion experiments on
tubes which were first plastically deformed by internal
pressure. Inside a special set-up a vertically disposed
tube was fixed which was stressed by internal hydraulic
pressure. The measurement of the pressure was accurate
to a degree 0.3,9P/o. The change in the tube diameter
under the effect of internal pressure was recorded in
six points along the,pircumference of the tube with an
indicator having scal&_"My~sions of 1 ~L. The torsion was
effected by loads applied't',e_a'3~ms of 1 m length. Seven

Steel 20 which was first annealed to obtain given
mechanical properties. The experimentally determined
curves show that in presence of a plastic deformation
in the tube, caused by internal pressure, the initial
shear modulus will equal the elastic shear modulus as
follows from the theory of plastic flow; thereby, the
degree of plastic deformation caused by the internal
pressure does not manifest itself greatly on the values
of the shear modulus and torsion. The coefficient of
proportionality between the torque and the twist angle
is strongly dependent on the magnitude of accumulated
deformation; these conclusions of the th~uory of elastic-
plastic deformations contradict the above mentioned
experimental data.

ABSTRACT- The article describes the results of an experimental study of the
long-term strength of drums and superheater chambers weakened by rows
of holes. The tests were made on tubular models with blind holes
drilled in the walls, as shown in fig.l.; with this arrangement
leakage was, of course, easily prevented. Themodels were made of
austenitic steel MMPT and of carbon steel St 20. The former were
of 54 mm outside diameter, with a wall thickness of 9 mm, and were
made in three formst without holes, with two longitudinal parallel
rows each of five holes, and with two rows of holes arranged diagonally~
The hole diameter was about 10 mm and the depth 2.5 mm. 'Me models
of steel St 20 were 46 mm outside diameter, with a wall thickness of
&= and were variously made without holes, with two rows of five holes
each and with other arrangements of holes, as indi2ated in fig.2.
Using a suitable test rig, the long-term strength of tees under
internal pressiLre was evaluated, and concurrent tests were made on
specimens in tension. Tests on the models of austenitic steel were
made at a temperature of 700 C and on thoae of carbon steel at 5000^v.,
The form lae used for stress determination are given for the various

arrangements of holes. The results, for tubes with and without
holes, are given in table.l., the strength factors and stresses
being calculated by means of the formulae given. Purther test
results appear in table.2. and the various data are plotted in
figs.3. and 4. for steels lEhISNOT and St 20 respectively. The
straight lines correspuud to test data for both tension and internal
pressure and correspond to the usual relation-hip between stress and
time to failurej it will be seen that the po~.nts for the weakened
tubes are in line with the rest. The experimental and calculated
strength factors for tubes weakened by holes are given in fig.5.
and a formula is written for the strength factow. A photograph of
an austenitic steel tube after failure appears in fig.6; the mode
of failure is described, noting that for tubes weakened by holes
there is more or less uniform stress-distribution over the load-
carrying section. Thus, the tests show that when designing
cylindrical chambers weakened by holesp the procedure established
for low tenperatures can be applied at high temperatures, even when
quite brittle steel is used. There are 2 tables, 6 figures and
4 literature references (Soviet).

ABSTRACT: The assembly scheme of the "chains" on the IFL2 machine is
used, so that two samples can be tested simultaneously. It may be
seen from a schematical drawing that the two samples under in-

holders by way of tensometers. The tensometers can be adjusted to
0.001 or 0.01 mm according to the tests carried out. Equality of
temperature of the two samples %Yas easily obtain,,id, ar-3 this test
system has been in use for more than three years, the efficiency
of the testing machines being doubled. it is recommended to use

axis creep is continuously measured during the test by means
of a densometer of the machine IP-2, and that the circum-
ferential creeD is measured by a periodical checking of the
sample diameter. This machine is nominally rated at a stress

TEXT: The paper is a continuation of previous work (Refs 2,
81 91 10). Hoff (Ref.1) has proposed a theoretical scheme for
calculating time to rupture based on the non-linear creep lawt
I = Acron (1)
where I is the uniaxial creep velocity, ao is the stress in
uniaxial extension, k and n are constanta. Hoff's method is
applied in the present paper to solve the problem of-rupture of a
thin-walled tube under the action of an internal pressure p and

Rupture in Creep Conditions for a Complex Stress;State
Eq (14). The equivalent rupture stress for the tube is obtained
from Eq (22); Eq (23) is the time to rupture as found by Hoff for
uniaxial extension with k obtained from Eq (24). The solution
assumes flow of the tube material with complete conservation of the
Initial geometrical form up to the point of rupture. It also
assumes that the material is homogeneous and isotropic and that
cracks are absent during the creep process. In practice, these
assumptions do not hold, and rupture occurs earlier than predicted
by Eq (21). The theoretical relationships have been compared with
experimental data.obtained on tubes of 12 MKhF steel at 595 OC~

some deviation of the points from the line is apparent. The solution
therefore gives rather rough quantitative valuesq but gives a
satisfactory qualitative picture of the rupture of a tube In
