ABSTRACT: In tires, shock absorbers, etc rubber is under frequent stress~
In many other products, like packings, the rubber is under
continuous static stress. in all these cases lb.-le most Im-
portant property of the rubber is fatigue resistance. In the
article, the fatigue resistance of rubber in relation to type9
degree of vulcanization, filling, and plastication is studied.
Natural rubber and the synthetic rubbers SID and SIKS-30, all
samDles without filler aid aith 40 parts of black per 100
parts of rubber weight, are tested. The results are giver, in
Figure 2. The filling has only a slight influence on the
fatigue resistance of the rubber. The fatigue characteristics
in stresses with alternating signs are determined by the rubber.

C~n the Relation Between the Fatigue .'esistance, Strength, Hysteresis and

of internal friction is distinctly shown by the curves in graph
5, where the index f OY /P (dynamic fatigue resistance at given
working capacity /tensile strength) was plotted as a Amztionof
the modulus of internal friction for various rubbers. The con-
siderable dispersion of the values is quite natural, as the
compared rubbers do not differ only in internal friction. Such
a dependence also holds for the index Eoy~ E.D (fatigue deforma-
tion/ specific elongation), as this relab on-changes in accor-
dance with f oy/11 (graohs I and 2). The data in table 1, which
was obtained by the woman graduate student, L. Pevzner, of
MITKHT imeni Lomonosova, permit still more definite conclusions.
The table contains the results of comvarative tests with vulca-
nized rubbers prepared on a butadiene styrene basis. The stan-
dard rubber mixture A of the table was varied by increasing
the sulDhur doses and reducing the amounts of added -filler.

tion of internal friction is also a very efficient method to
increase the working capacity of rubber, as the lower the inter-
nal friction, the lovier also the temperature, which develops
in the ready product as a result of hysteresis. In order to

TITLE- On the Relation Between the Phenomena of Rupture and Tear in
Rubber
PERIODICAL: Doklady Akadei,,iii nauk SSSR, !,.~159 2 Vol 128, Nr 1 ,
pp 75 - 77 (USSR)
ABSTIMT: In some previous papers (Ref 4) on the "tear" of rubber an
approximate theory of this phenomenon was developed. It yields-
a auantitative relation between the so-called characteristic
energy T of tear and the specific energy E of rupture. One of
the principal errors of this theory is the neglect of the
statistic nature of strength and of the resultant dependence
of the latter on the size of the sample under investigation,
or on 'the value of the volume to be deformed. However, break ng
tests exhibit the following special features: Due to artifi.
cial concentration of tensions, destruction always takes place
in a definite, minute volume at the end of the increasing cut-
This is why the results of breaking tests can be compared only
if the essential difference in the size of the samples under

-,,;ith decreasinz size of the above samples is easily explained
b3~ the -- tatistic theory as less dangerous damages occur in
smaller volu--ies. This assui.,,ption is confirmed by several ex.
perimental data. The ip-proximate raethod of extrapclating the
q-ialitative esti:aation of the true tensions produced at the
end of the cut was eLiployed in an investigation carried out
in the authors' laborato--y. Various kinds of samcl~~s were sub-
j--ct,zd to breaking tests. In most cases, the (obvicusly too
small) values of the desired Lension exceeded those obtained
frou-i Ordinary breakirl.- tests. The characteristic energy of
tear cannot be ascertained from the random value of the elastic
ener-y E (result-i-Iry from ordinary breaking tests), but from a
certain limit E., which corresponds to the minute size of the
volume deformed at the end of the increasin:7 cut T=dE =

TITLE: The Friction Between Rubber and Hard Materials
PERIODICAL: Kauchuk i Rezina, 1960, No- 5, PP. 34 - 37
TEXT; The signific IT-Ice of developing a method for increasing the
wear-resistance in tiresNof automobiles and aircraft is stressed, The
phenomenon of friction in soft, not completely elastic material (in this
case rubber), against a hard rough surface is studied here. The main point
in the study is the fact that the local deformations, to which the rubber
is subjected, are completely elastic. Since the model must explain the
occurrence of friction forces, no specific surface "friction forces" are
taken into consideration. In order to analyze the phenomenon of friction,
the author makes several assumptions, using as his model the surface of a
hard body represented by a relatively regular system of alternating cavit-
ies and humps and a rubber sample sliding along this surface (Figure 1).
The assumptions are confirmed mathematically, using Kelvin's formula for a
tensile-elastic medium. Equation (5) confirms the experimental data ob-

tained on the relationship between velocity and time of the moving force
in sliding and vibrational friction. The investigation of the relationship
between the friction coefficient of rubber along/a hard rough support and
the indices characterizing its tensile-elastic\troperties is of special
interest. The friction coefficient on steel depends on the main factors
determining qualitatively the rubber composition as well as the coefficient
of resistance to vibration of the rubber roller on the freely rotating
steel roller, pressed onto its surface. On the whole, the experimental
material gathered agrees favorably with the original assumptions made, con-
cerning the effect of the composition on the friction coefficient of rubber,V
on steel, and as to its tensile-elastic properties. All the facts given
about the elastic-hysteretic nature of the external friction of rubber on-
ly show the main factors in the region of friction of the rubber on a hard
rough surface can be qualitatively explained by a purely mechanical view-

4) Recommendations of more effective methods for high-speed control of
rubber mixtures. 5) Modernization and introduction of new apparatus for
testing of various forms of aging. 6) Increasing the productivity of the
instruments intended for mass testing, automation of the prime operations
and analyzing the results of the measurements. 7) Extension of research
on the study of the mechanical properties of elastomers and introduction
of physical testing methods for complex indices, such as dynamic elasticity

This makes the apparatus easy to operate. To eliminate the possibility

of measuring deformation on this kind of specimen are elaborated, In the

TEXT: An installation guaranteeing satisfactory accuracy and reproducibility
of measurements even at nonuniform 0 3 distribution in the working chamber is
described. In order to exclude fluctuations in the 0 5 concentration, the
case containing the samples revolves at a rate of 2 rpm. The contactle2s
transmission of torque from the Warren motor is attained by means of ~- ::~a,--
netic clutch. [Abstracter's note: Complete translation

TEXT: To find the most efficient method of determining the scorching
capacity of rubber mixtures, the authors compared the characteristics of
the most usual laboratory methods with those characterizing the behavior
A
of mixtures directly during the technological processing i scorching is
essentially affected by the following factors acting during the preheating
of mixtures: deformation, its amount, rate, and periodicity; tempe~*ture
and its duration; medium of preheating; volume of the prepared mixture to
be preheated. It is most convenient to determine the scorching capad~ty
of rubber mixtures by means of shift plastometers. [Abstracter's not6:
