TEXT: The author investigates a method of testing flat metal specimens
(1-4 x 10-40 x 100-200 mm) by way of.determining the resonance length of the
specimen fastened as a cantilever beam at oscillations excited by an electro-
magnet (cross-section of the core = 20 x 30 mm, required power = 40 W), supplied
with commercial AC of 50 cps. In the device recommended for the tests, the free
length (1) of the specimen can be varied by readjusting the fastening and is
measured with a nonius-equipped ruler, while the resonance point is determined
visually or by ear by the abrupt rise of the oscillation amplitude. The modulus
of elasticity (E) of the specimen is determined by the formula
E = B"

where N = oscillation frequency (at f = 50 cps N = 100), h = thickness of the
spe cimen, specific gravity of material, g = gravity acceleration, B = the
coe-ftficient depending on the fastening method of the specimen. The accuracy
of the method amounts to 1-1.5%. A similar device is suggested for metal
fatigue tests. A specially shaped plate made of the material to be tested is
fastened in such a way that the free and possesses the resonance length which
is oscillated by an electromagnet. When fatigue cracks appear, the oscillation
amplitude decreases rather abruptly and this determines the termination of the
test. The number of cycles is calculated by the formula n = 6000 t, where n =
number of cycles, t = test period in minutes. There are 10 figures, 7 references.

.ABSTRACT: This paper was lectu-ad at the Scientific Conference in "lie
Kazanskiy aviatsionnyy institut (Kazan' Aviation Institute) in
1950. The applicati(,,i of the radiotechnical method (Ref 2) of
determining elastic constants requires a complicated radio ap-
paratus. In the present.case, the construction was simplified,
and an alternating current was used for exciting the sample os-
cillations. The testing methods were slightly changed as the
by'a change of the free sample length. The
resonance is attained
,
sample is fixed-in a special electrotechnical device (Figure),
and the resonance moment, is determined by the maximum oscj._1-
lation armlitude as ni~~tioned above. The elasticity constants
E and G can then be computed by an equation (1). This electro-
technical method enables determinations of the elasticity con-
Card 1/2 stants with an accuracy of 1-1.6%. In the present case, two

de-ices were developed for tests of this kind where rectangular
samples with constant cross sections can be tested. The sketch
of one of the devices shows that the oscillations are produced
by an electromagnet which is fed by alternating current. The
second device was made according to a scheme (Ref 4)- But
practic,'e showed that better results are obtained with the first
device. There are 1 figure and 5 Soviet references.

TEXT: Specimens 6 mm in diameter and 18 mm long from the steel grades
+W -415 (Ei-415), 4oXHMA (4oKhNmA), 30X[-(-,4 (30KhGSA), 45 and 15, and from
copper and brass were subjected to repeated static tension and compression and to
repeated tension at a given load up to destruction. Based on the results of
these tests the author investigated the mechanism of the process of static fatigue
- fatigue failure at low loading rates. The tests confirmed the hypothesis on
the accumulation of residual deformations and the assumptions on the equality of
breaking points at static fatigue and single tension. It was found that
materials (e.g. bras 's) having a compression curve which is lower than the tension
curve cannot be destroyed by static fatigue if the loading cycle is symmetrical.
It was established that, for a cycle with the given deformation, static fatigue

suggests to carry out static fatigue calculations by a method which is analogous
to the calculation of creep. There are 5 references.

where K is a coefficient depending on the overload of the material, an the type of
deformation and on the effective coefficient of the concentration of stresses of a
sample vith an initial fatigue flaw.
The change in the force conditions connected to the changes in the stiffness
of the sample is characterized by the stability coefficient K, whose magnitude is
eqQal to one in the case of cycles with given load, while in the case of given
defonnation cycles its value is given by
Kc = Cn - 1 (3)

where A - a coefficient dependent on the dimensions and the shape of the sample,
and the ifidth and orientation of the flaw; Cn, Co - stiffness of the injured origi-
nal sample.'From what was said above it follows that D takes the form
D = Do exp (Kn) (4)
for a cycle with given'loads, and
D = Do exp LTI-A)Kn7 (5)
for a cycle with given deformations. At the instant of final breakdown, D = Dp in

Experimental data obtained by the author and other investigators were general-
ized -for the purpose of checking Equationr, (4) and (5) and for the determination of
the values of K and A.
The experimental data concerning the development of flaws agree with the expres-
sion (4) and (5) during the period correspondibg to a steady state of development.
The final stage does not obey the indicated regularities. The history of the load-
in- and 'the magnitude of excess load prior to the appearance of the flaw do not
affect its speed of propagation. A fatigue flaw can grow at stresses which are
below the fatigue limit. M. Ya. Shashin.

ABSTRACT: A method is proposed for determining the propagation speed of a
fatigue crack, by measuring the variation in 'the vibratign freq4ency of the sample.
Ca
Vie method is based on an erq3irical relation between the sample.vibration
L-cquency and the metal failure (expressed in terms of the variation in the
i;ioment of inertia of the unbroken part of the sample). The tested samples were i
made of steel 20. A special testing kaparatus was built for this purpose (see
F-L6g. 1 of the Enclosure). It.can operate either under automatically produced
V
ibrations or it can be activated by a sound generator ZG-lU (1). The auto-

vibration system consists of the sampld:(2) fixed in the clamp (3), an indicator
(4), a phase Changer (5), an IWU-100 amplifier (6), and an electromagnet (7). 1
The frequency is registered with a meter (8) or with the sound generator (1) and
tile EO-7 oscillograph-(9). The amplitude meter (10) measures the amplitude of
the sarkple vibrations and of the registering -2 galvanometer (11). The indica- I
SG
kor readings are r6gistered by the galvanometer (11). The experimental results
f
Showed that a fatigue crack may develop'under stresses considerably lower than
the fatigue limit 'stress. There exist-9' hawever., a minimum stress below which a
fatigue crack does not increase and w1`i'icYh depends on the type of the sample
impairment. The process of loading and the magnitude of the overload before the
nomerr- of metal failure'do not practically affect the propagation speed of a crack.

steel [0. 35-0. 427o C, 1. 35-1. 657o Cr, 0. 15-0. 25% Mo] impregnated with Al.
The nitriding, done in cracked ammonia at 500-530*C for 22-24 hrs,produced

ABSTRACT: in an earlier paper the authors investigated the properties of
difffusion layers produced by corrbi*g chemical treatment with heat treatment, and
t
they con't-inue their research by reporting additional test results. Sleeves,
checkers and segments were e_%posed to bydrodbrasive wear. The treatment consisted
off calorizinZ (950-10000 C) for 12 hrs, titanizing (1080 C) for ld hrs.,
(1080-1100 C) for 2.1 hrz. and chromizing (1150 C) for 8 hrs. ALI

TITLE: Performance of Squirrel-cage Induction 1"Jotors at Low Ambient
Temperatures (Rabota asinkhronnykh korotkozamknutykh dvi.-a-
teley pri nizkikh temperaturakh okruzhayushchey~sredy)
PERIODICAL: Elektrichestvo~ 1959,. Nr 3,~ PP 56 - 58 (U33R)
ABSTRACT: When a choice is to be made of motors with a maximum power
of 5 kw, which operate on building sites at temperatures ranging
from +350 to - 200C (according to the supple%ent to GOST 186-52)1
sometimes even to temperatures as low as -500C~ the modifica-
tion of the characteristic curves of such motors must be taken
into account. This is an investigation of the problem. The modi-
fications of the characteristics are studied of motors, uhich
are due to ambient temperatur6 changes,and-,--of motors of a general
industrial design, which operate at temperatures down to -200C.
The question is raised and discussed, whether special designs
would be expedient for motors~ which operate under temperatures
up to -500c, and finally motors which operate under ambient
temperature changes from +50 to - 500C. Summarizingly the following
Card 1/3 statements are made: 1) If temperature changes from -20 to

Performance of Squirrel-cage Induction Motors at Low SOV/105-59-3-1 2/27
Ambient Temperatures
+350C are encountered (temperature interval 550C) motors of
a general industrial design can be used. At lower temperatures
checks must be made, whether the starting torque corresponds
to the braking torque. If it is necessary, the deviation of
the starting current from the rated value given in the cata-
log must be taken into account. 2) The temperature ranges of
from -50 to 4100C and from -50 to +500C do not seem appropriate
in the case of motors of a low capacity. The use of frost-
proof motors, which are intended for such purposes, guarantees
a reduction in weight, of outside dimensions and of raw material
expenditure. This also results in a reduction of running costs
because of an improvement of the power indices. 3) It proved
to be advisable to introduce the concept of standard or cal-
culation temperature in the design of conventional industrial
motors and of low-temperature motors. It is specified as the
temperature, where the ambient temperature dependent character-
istics must agree with the values given in the catalog. There
is 1 figure.

ABSTRACT: The brittleness of isotactic crystalline polystyrene (1)
hampers industrial-application of. this material. Attempts to reduce
the brittleness by plasticization resulted in a sharp drop in me-r'.-
c.hanical strength because of,the formation of large morphological
forms (supramolecular,str 'uctures) and distributlon of the p-lasticizer,.

properties of I depend on the amount of plasticizer, and that there'
exists an optimum plasticizer concentration which insures comparative]Ly~

concentration is 4.5 moL% (tensile strength, 286 kg/cm2 at 20C and

Title The development of strains during the formation of lacquer and var-

Periodical : Ehim. prom. No 7, 392-397, Oct-Nov 1955.
Abstract : Developed new methods for determining strains in lacquer and var-
nish films: the strain is measured directly on paper strips after
the coating has been applied or by determining the curvature of a
thin metal plate. Found that the strain does not depend on the
chemical nature of the coating or the chemical processes which take
place during drying. On the other hand, the temperature has a strong
effect. The mechanism of the formation of strains is interpreted on
the basis of the experimental data found. Sixteen references; 8
