ABSTRACT: The stability proble;.i for sandwich plates and shells is
usually solved in linearized form. By this means
sufficiently simple equations for plates (Ref 1) and
shells (Ref 2) can be written. But it is known that
for simple shells the solution according to normal
linear theory can lead to siEnificant reductions in
the load after loss of stability. Equations for large
displacements have been obtained for sandVich plates
(Ref 3) and shells (Ref 4). In these equations the
bending stranSth of the exterior layers and the normal
stresses in the filler are neGlucted. In the present
paper the equations foi- larL~e displacew,~nt for sandwich
shells are obtained -ahich are free from th-ase omissions.
In deducing the equations it is asF;u:.-,ed that the
Kirchhoff-Love hypothesis is valid for the exterior

with consideration of shear and transversal stresses
(tear-off) which arise along the surface of the junction
between the outer layers and the core. Calculation
formulas were obtained for plates operating under
longitudinal compression and longitudinal and transverse
bending.
3. Kuxzhin,-L,,M. Large Deflections of a Cylindrical Sandwich
Shell 39
A system of nonlinear equations for ultimate buckling
of cylindrical sandwich shells is obtained by the
variational method. The problem of longitudinal
compression of a cylindrical sandwich panel simply
supported along its four edges is solved according to
the nonlinear theory. The results permit the conclusion
that load reduction following loss of stability is
smaller for sandwich shells with a light core than for
single-layer shells of the same thickness.

Stability equations are obtained for a cylindrical
sandwich shell consisting of two thin outer layers and
a corrugated middle layer. The problems of stability
of a curved sandwich panel simply supported along
its four edges and of a cylinder under compression are
solved.

This paper analyzes the stability of a cylindrical
sandwich panel with a light isotxIopic core under
uniform longitudinal compression for a case where
the transverse edges are fastened and the longitudinal
edges are simply supported.

A formula is obtained for calculating curved sand-

consideration of the natural bending stiffness of
the outer layers. The domain Is established in which
the assemption of this btiffness being equal to zero
is applicable.
7. Galkin, S.I. Torsion of an Open Cylindrical Shell Rein-
forbed by Buikheads 85
Torsion of an open cylindrical shell reinforced by
bulkheads is considered in this paper. The solution
is obtained without introduction of additional hypotheses
aside from the general assumptions associated with
representing the operation of an open shell as moment-
less. On the basis of the solution the limits of
applicability are shown of the hypothesis of warping
which has been widely used in problems of calculating
open shells under torsion.
8. Galkin, S.I. Torsion and Bending of a Circular Cylindrical
Shell. Reinforced by Elastic Bulkheads 102
Card 5/7
Problems in Calculating Aircraft (Cont.) SOV/2606
This paper investigated the state of stress of a circular
cylindrical shell which is reinforced by elastic bu2k-
heads and loaded along the edges by an arbitrary system
of axial and tangential forces. Calculation formulas
are obtained which permit calculating all elastic-defor-
mation components for various boundary conditions at
the edges of the shell. The effect of self-balancing
forces on the state of stress of the shell as a function
of the stiffness of the bulkheads was investigated. It
Is shown that the self-balancing stresses do not decay
very rapidly; the zone of their propagation into the
depth of the shell is practically equal to the length of
the contour of the transverse cross section of the shell.
A calculation example is given for a shell under torsion
allowing for elasticity of the bulkheads.

unsymmetrical heating of such elements through the

case of different thicknesses of flanges. Solution
of the problem Is given under the assumption that
physical characteristics of the material and the

TEXT: A system of non-linear differential equations was obtained for the
final deflections of triple-layer cylindrical shells with rigid filler and car-
rier layers of the same thickness by means of the variation method. The validity
of the hypothesis by Kirchhoff-Loew was assumed in the deduction of equations for
carrier layers, and the linear law of change of displacement 'In vertical direction
assumed for the filler. The transversal compression of the filler was not cdn-
sidered. The shell was considered to ~6e slanting, and for the deformation at the
final deflections are used the known simplified equations. The material of the
outer layers is uniform and isotropic, the filler transversally isotropic.
Poisson's'ratios of all the three layers were taken as equal. The variation

equation of the triple layer shell is written in the form: (3(vl+v2+V

and ottom layer respectively, V = potential energy of deformation of the filler,
A = work of outer forces, appli2 to the contour of the triple layer panel, q
= outer pressure, w = deflection. From the variation equation is obtained a
system of five differential equations of equilibrium in displacements and boundary
conditions. Introducing the function rP of stresses and function Y of displace-
ments the author reduces the mentioned system to three differential equations in
variables i,Y, and w. The problem of longitudinal compression of a triple-
layer square cylindric panel, free resting along the found edges was solved ac-
cording to the non-linear theory, and the function of deflection was selected
in the form w = f sin IIX sin An equation was obtained which connects the
a b
value of the compression load and the magnitude of deflection in the middle of
the panel. The conclusion is drawn that the decrease of the load after the loss
of stability is smaller in triple-layer shells with light fillers, than in single-
layer shells of the same thickness.

ABSTRACT: Several Investigations dealing with the question of the thermal stabi-
lity of cylindrical shells equipped with cooling diaphragms have appeared In the
literature during recent years. it Is known that heating of a cylindrical shell.
with a frame restraining its thermal expansion produces circumferential compres-
sion stresses which may result In the loss of Its stability. The thermal stabil-
ity of clamped cylindrical shells was investigated by W. Zuk. but the results ob-
tained by W. Zuk cannot be accepted for long shells, because of the rough approxi-
mation of circumferential and bending stresses; his value for the coefficient K
differs substantially from the value of 6.41 obtained in the present paper. The
attempt by Jones to improve the results of Zuk's analysis was not successful,
Card 1/3
ACCESSION NR: AT4oiO249
since his value for K was 12-7. The present paper presents a solution for the
problem of the thermal stability of circular cylindrical shells with tubular
diaphragms (for circulation of the cooling liquid.) The author analyzes a semi-
Infinite Sihell, since the tensions resulting In the loss of shell stability at-
tenuate with distance from the diaphragm, including cases In which the shell
either is clamped or rests freely on the diaphragm. In the solution of the prob-
lem, use is made of stability equations which take into consideration the state
of the shell preceding the loss of stability. The critical temperature during
heating of a shell with a diaphragm Is given by:
k h
(i _V)
where R is the radius of curvature, -(- the coefficient of linear expansion,
T - temperature, and K - 6.41 for a clamped shell and 12.2 for a shell resting on
the hinge. The critical value of the temperature as found by formula (1) is
sufficiently large so that the solution of problems Involving performance of the
material beyond the elastic limit has no particular meaning. The reason for this
is that in the performance of a shell material in the area of maximum stress, as
encountered beyond the elastic limit, the rigidity of the frame itself Is de-
creasing and the shell becomes more pliable. To prove the above statemento a

under conditions beyond the elastic limit. For a clamped shell, the calculated
value of the critical temperature (according to formula 1) was 440C. Actually,
no loss of stability was observed at 620C. "The author would like to thank

of the theory of both curved and uncurved shells. The solutions are obtained with consider-

ABSTRACT: A study was made of the stability of a closed cylindrical sandwich
shell under torsion. A solution which is based on equations for steep shells and
which takes into account the work moment of the outside layers is obtained. The
stability of hinged shells of finite length under torsion is examined. It is demon-
strated that a transition to a rigid filler and a shell of asymmetrical structure is
achieved in the same way as in the case of a long shell. [Translation of abstract'j
