AW1191ACT: TheLauthors investigated the system of equations governing the struc-
ture of shock waves in incompletely ionized hydrogen with small admixtures of
heavy elements (responsible for de-excitation of the gas). The loss of energy
on ionization of the hydrogen is considered, and the radiation in a discontinuous
spectrum is examined. The energy loss during excitation of discrete levels of
the hydrogen atoms was not considered since it dopends on the optical thicknoss
of the shock wave front in thG Lyman series, amd when this is large t~~ loss is
relatively small. Numerical computations were made by means of an electronic
computer to express the relations between shock wave velocity and the maximum
electron temperature, the width of the front and the width of the do-excitation

ABSTRACTs In view of the highly intriguing nature of the phenomena occurring in
the center of the front of a strong shook wave, the author investigated the strac-
ture of shook waves in a partially A2nj~e~das.!P Since equations of kinetics, of
special importance to shook waves in an inconpletely ionized gas are required,
the calculation of the collision term is fundamental. The author performed calou-
lations of co33isions between atoms, ions, and elgetrons, on the basis of the
equation of kinetics given by Landau, L. D. (Zhurnal eksper. i teor. fiziki, 7,
'103, 1937), and derived expression (4) of the Enclosure. He notes that when m sub

ABSTRACT: With periodic shut-downs during the process of operation the shells
of high-pressure boilers are subjected to uneven heating, which creates
temperature stresses in the shell walls. The paper presents an ac-

mal stresses in the walls of a f reely- supported cylindrical shell under
the condition that the temperature varies only along the contour of a
cross section in accordance with the law t --- t(s) (where s is the arc

ABSTRACT: The authors present the solutioq of a problem on thermal
conductivity for an infinite strip iT1 which the temperature of
the bottom surface varies at a co-astant rate, the side surfaces
are thermally insulated, and the apper surface has a heat
delivery into a constant-temperature medium; this solution
contains a series of functions wh: ..ch depend upon the roots g7of the
transcendental, " equation tan ~il = - ji/h, where 1. is the
thickness of the strip and h is the relative heat-exchange
coefficient. For the above-indicated temperature field the
problem is solved for the thermoelastic equilibrium of an
Card 1/2 infinite strip the surfaces of which are free of outside forces;

the boundary conditions on the top and bottom surfaces of the strip are ful-
filled rigorously, while those on the lateral surfaces are fulfilled in the sense
of de Saint-Venant' s principle. Even though the temperature field is tran-
sient, the authors disregard the forces of inertia and discuss the problem as
quasi-static. The stresses obtained (as well as the temperature) are in
direct ratio to the heating rate. With ideal thermal insulation ( h = 0) the
stresses at a certain moment become practically constant. The stresses
reach their greatest magnitude on the heated surface.

ABSTRACT; The author has derived equations for determination of integral
characteristics of temperature in thin shells, assuming that
the thermal dissipation from the surface of the shell pro-
ceeds according to Newton's law. In a case of stationary
thermal conditions and negligible heat emissien from the

for solving the boundary problem for-the shells of revolu-

ABSTRACT: When investigating the fatigue strength of steel samples it
became evident that in a torsion with alternating sign
and large amplitudes the breaking of machine part begins
with the development of a high number of longitudinal surface
cracks which finally unite to transverse cracks(see Fig 1).
When heating the samples intensively the breaking occurs
in consequence of the temperature stresses. The authors
investigated cylindrical samples under the influence of
torsion and t~mperaturqincrease. The formula for the
relation between the occurring stresses I and the angle of

samples depends among other things on its diameter; in
investigations on torsion e.g.it was ascertained that the
increase of the diameter from 10 to 200 mm 0aused a decrease

ABSTRACT: In fatigue testing of components, it is sometimes found
that failure occurs at an unusually low stress, and that the
failing load may depend on the size of the specimen. In the
present paper, the effect of internal friction on the fatigue
strength is investigated. Internal friction in a specimen
undergoing test leads to the evolution of heat which in turn
leads to the development of thermal stresses. Equations are
obtained for thermal stresses in a twisted and a bent speci-
men. It is found that the radial and axial stresses in torsion

TEXT: Consider first the stressed and deformed state of an
elastic isotropic body under a given system of forces and in an
inhomogeneous temperature field. General equations of motion of an X
elastic medium which take into account the hydrostatic thermo-
elastic effect (energy dissipation) suggestq if they permit of a
solution$ following Papkovich (Ref 7), an expression for the
displacement vector in terms of another vector 4~ ~ which can be
expressed as the sum of three terms. There is a discussion of the
equations for these terms, and the simplifications for the quasi-
stationary problem. Suppose now that there are in an infinite space
certain factors which are periodic in time causing a definite
thermo-elastic state. These factors may be sources of heat
distributed in some manner throughout the body, or given body forces.

TEXT: A thermodynamic system, represented by a single-phase n-com-

equation for this system is

The system is characterized by five groups of thermodynamic con-
stants, namely those relating to elasticity moduli# linear expan-
sion, stress, diffusion and heat capacity. These constants consitute
a complete system of physico-mechanical characteristics. By means
of these characteristics and equations of type (1), it is possible

to set up tables of all possible first derivatives of the parameteis
of the thermodynamic system, as well as tables of the characteris-
tic functions with respect to the independent variables. This is
done by the Jacobians method (Ref. 6: P.A. Cravifordp Am. J. Phys.,

Diffusion in a non-uniformly heated strained layer
in the presence of mass-exchange with the ambient
medium

TEXT: The relation between the processes of diffusion, heat con-
duction and deformation in a binary isotropic solid solution is
considered for the case of an infinite layer of'thickness 2 1. The
differential equations and the boundary conditions for these pro-
cesses are set up; thereby certain simplifying assumptions are
made. The infinite layer is subjected to stretching and bending;
is heated by convection with the ambient medium; an exchange of
At
atoms may take place between layer.and medium. The system of equa-
tions reduces to two:

t
lations are set up. In order to determine the stressed-strained
state of the layer, it is necessarY_--,,,to find the 'distribution
c(x,--7) of the solute and the tempbra~ure distribution t(x,?,I. These
are obtained by solving system (5)'-and the corresponding boundary
conditions. The formula for c(x,--L), thereby obtained, is consider-
ably simplified by assuming that the settling time of the thermal
regime is considerably smaller than that of the diffusion process.

The simplified formula shows that the change in the concentration
of the solute is a result of 3 different diffusion proces~�es: The
first oroce~ss is due to the difference in chemical potentia1sy
the second,to the strain gradient (due to the.force P and moment
and to the strain due to the temperature variation, the third
L. -ion of the so-
is thermodiffusion. In the case of vacuum evaporat,
lute the obtained formulas are modified (by setting the chemical
potentials~equal to zero). In a stationary process, the stresses
in the layer arise as a result of the external forces only. The
strain comp!onents consist of three terms; the first is related to
the force P and the moment M, and the other two to the diffusion
.processes a'nd the non-uniform heating. From the 'strain tensor,
corresponding to the state following the removal of the applied
load, it is~possible to calculate the radius of curvature of the
middle surface of the layer; two formulas are obtained for the ra-
dius of curvature, corresponding to the residual strain. These
formulas can be used in the*experimental determination of the phy-
sico-mechanical constants of materials.

TEXT: The purpose of this study was the determination of non-stationary
temperature fields in hollow cylinders and spheres and the calculation of result-
ing stresses. The authors determine the temperature field in a hollow body (in-
finite cylinder, sphere) whose surfaces exchange heat with a surrounding medium
of constant temperature in accordance with Newton's law. The-temperature of a
...-.medium'filling up'the body varies by a periodic law. Using the equation.of heat
and corresponding boundary and initial conditions the general solu-
tion of this equation is sought for in the following form:

where ~ is dimensionless radial*coordinate r/H2 (R2 is external diameter of the
body); ) = I pertains to cylinder, 9 = 2 pertains to sphere. After a certain
time interval,"asymptotic thermal"conditions set in and the temperature at any
point oscillates with the same period as that of the inner medium, but with a
different amplitude and phase shift. Rigorous solutions are found for the case
of a hollow cylinder in terms of Tompson functions, and for the case of a hollow
sphere in terms of hyperbolic functions. As an example, a practically important'
case OIL- pipelines in thermal electric power stations is consideredi when the
outer surface of the cylinder (pipeline) is thermally insulated. The second
problem dealt with is the determination of the stressed-strained-state of the
bodies subjected to forced thermo-elastic oscillations-caused by periodic changes
of temperature according to the same law (5). To calculate stresses, formulae
derived by L. I. Lurtye ("Prostranstvennyye zadachi teorii uprugosti", Spatial
probl Iems of the theory of elasticity, GITTL, 1955) are used. The expressions
for radial and tangential stresses are inserted into the equation of equilib-
rium, and the differential equation obtained for displacements Uo(pt) is solved.

Then, using this solution and expres�igns for stresses given by.Lur'ye, the
authors derive formulae for radial I-Pk") and axial Uz'-"stresses. For the latter
case, conditions of axial strain are of importance. Two cases, when the cylin-
der ends are fixed and free, are considered and corresponding formulae for axial
stresses are presented. The formulae are considerably'simplified when inertia
forces can be neglected. Comparing the results with thetknown Timoshenko's
formulae for a quasi-stationary problem, the authors conclude that the formulae
dprived in the present article represent a geneialization of Timoshenko's
f6rmulae extended to the case of steady-state conditions of forced oscillations.

On singular solutions of the dynamic problem of thermo-

TEXT: The thermoela,9tic state of an infinite medium is considered,
subjected to concentrated periodic forces. The author proceeds from
the system of differential equations of thermoelasticity which make
allowance for the influence of the strained state on body tempera-
ture. The forcesp concentrated at one point, are considered as body
forces in the limit which act within an infinitely small neighbor-
hood of the point. 'This makes it possible (by using the 6-function
apparatus) to reduce the problem under consideration to solving the
system of thermoelastic,equations in the presence of the specified
forces. The original system of equations is

-ABSTRACT: the atomization of liquids by means of a gas stream is used in various
technical devices such..as nozzles, coolers, reactors, absorbers, etc. Two formulas
have been previously derived for the approximate determination of the hydraulic losses'
in thr-be devices. However, these two formulas account for only the loss due to the
energy expended in accelerating the droplet's to a given velocity, while'the entire
pressure loss actually consists of energy used,for the deformation of the liquid
jet, droplet formation, acceleration of the droplets, the friction of the gas on the I-
surface-of the liquid, and displacement of the liquid film. Therefore, in the presents
study, experiments were made to take into account these other factors. An assenbly
was*used in which an air stream entering through a diffusor atoniomizes the liquid
(water) which is injected through radial orifices (0.3-3 mm in diameter) into the
