ABSTRACT: After asurvey of numerous papers by other authors dealing with the
stability and free vibr4tio,ns of thin isotropic supported cylindrical and conical
shells under various boundary conditions, the present authors come-to the conclusion
that the formulas so far suggested for the determination.of the frequencies of.
vibrations of the conical shells are cumbersome, and that their applicability range iw,
not well defined. Zia present.paper investigates the stability and small extra-axia"'~~-

ABSTRACT: An anology is established between problems of free vibrations of a simply
supported three-layered sphericnl shell restricted in plan by rectilinear segments
~with the well known problem of oscillations of a plane membrane. The structure of'.
the shell is considered to be asymmetric with respect to thickness. Thematerials 0 f
'the layers are isotropic with equal Poisson ratios. The transverse compressibility
of the filler is not taken into account. Theorems are formulated relative to the
fundamental frequency of a simply supported, mildly sloping three-layered apherical
shell and a plane-three-layered plate, the~validity of which is proved for a plane
membrane. Axisymmetric vibrations and the stability of sloping spherical domes in
plan by a circular region are also exainined. (Translation of abstract] A. G.

TEXT: In the case of metals at not too low a temperature and
electrons in the energ--?- range of the order of kT from the
Fermi, surface the probability of, electron-phonon collisions
is much greater than the probability of electron-electron
collisions. Hovrever, electron-electron collisions become
important in the case of conduction-band excitation energies,
greater than kT (Ref. 1: Landsberg, P.T. - Proc-Phys-Soc.,,
1949? A062, Bo6; Ref. 2- Blokhin, M.A., Sachenko, V.P* Izv.

Eq. (10) of Ref. 2. The present authors report an attempt
to Compute the Drobability of radiationless transitions without
the use of the Borri approximation. The problem is formulated
as follows. Consider the excited state of the conduction

TEXT: The adjustment of the newspectrometer is comparatively simple and
takes only a few hours. The crystals can be taken out of the apparatus
without disturbing the adjustment. The distance between the rotating axes a.f
the crystals is 100 ram.. The focus of the X-ray tube is.300 ram distarlt from
,the rotating axis of the first crystal. The distance cf the rotating axis cf,
the second crystal from the window of the Geiger counter is 100 mm. The
second crystal can be rotated by � 1-50 from th'e middle position reading
accuracy 0.010). The spectrometer is not adjusted by means of the,crystals
but by glass plates. After adjustment, the crystals are inserted to deter-
mine:,the CuKc~i - line and the angle.between crystalsurface'and lattice
planes. Eight horizontal plates were builtinto the collimator to reduce

the-vertical scattering of the beam to a minimum and yet to obtain high
radiation intensities. A beryllium plate inserted between the collimator
andthe first crystal is to eliminate the focus drift and the effect of
feeding-voltage fluctuations. It was difficult to choose the suitable
crystals since extreme optical uniformity is required, and the angle between
crystal surface and lattice Dlanes shall be as small as possible. Its
maximum was 105". Plates parallel to (10fO-) and (11 rO) zere cut from
various quartz crystals and investigated after etchin . The purity of the.

two crystals is determined.by the v7idth,of the reflection curves.* The
quality of the plates is estimated from the shadows produced by deviations,
of the refractive indices. A final examination carried out by means of a
polarization system indicates optical inequality of the plates by brielt
spots. There are 6 figures and,_6 references: 1 Soviet and 5 non-Soviet.

ABSTRACT: In continuation of previous theoretical and experimental investigation*.
of transition metals of the palladium group (I.G.Shveytser, V.P.Sachenko and I.Ya.

spectra of Mo and Nb are compared, and their differences are interpreted in terms
of the energy level distributionsin the metals as calculated inthe orthogonal

from.the earlier paper. The Nbemission spectrum was taken from work of U.I.Korsun-
.-.!skiy and Ya.Ye.Genkin (Izv.AN SSSR,Ser.fiz.25,1028 1961) and,the Kb LI11 absorptloim~

similar, but the following differences are.noted: the W2,emission band of Mo Is
both wider and more symmetric than that of Nb, and the first LIII absorption line
of Nb is wider than that of Mo and its maximum is located.farther fron..the absorp-
tion edge. Since no self-consistent wave functions are available for Nb, and since
hogonalized Slater functions proved to be insufficiently accurate, th
ort e atomic
parameters of Nb required for the orthogonal plane wave calculation, namely the
Fourier components of the atomic potential, the orthogonaiity.coefficients, and the
energy eigenvalues, were obtained by extrapolation.from those of Mo. The extrapola-
tion of the ener~;y eigenvalues was performed with the aid of Moseley's law,
that of
the orthogonality coefficients by means of Hartree's scale transformation of the
wave functions, and the Fourier components of the potential.were extrapolatedby~
first calculating their dependence onthe atomic number with the Fermi-Thomas model.
Thirteen orthogonal plane wave functions were employed in the calculation of the.,
energy levels; the method of calculation is described in more detail in the earlier,-',,.
paper. Considerable differences were found between the level distributions in Mo
and Nb. In particular, the maximum density of d levels occurs near or below the Fer-
mi surface in Ito and considerably above it in Nb.,The LIII spectra of the two metals
are discussed in some detail.in
relation to,the level distributiona, and all the-
difforences noted abovo,are successfully interpreted in one case (the width of the

TITLE: On the Theory ofPlastic-Elastic Stability of
Bimetallic Shells
PERIODICAL: Izvestiya vysshikh uchebnykh zavedeniy, Aviatsionnaya
tekhnika, 1960, Nr 2, pp 69-79 (USSR),.
ABSTRACT. In Ref 1, on the basis of the theory of deformation and
the theory of plasticfloi%r, were obtained the fundamental
physical relations for bimetallic shells. The surface is
a.soldered one of two.layers. The solution of the same
problems is given.in,this paper, but the surface is
taken such that with respect to it the physical relations
linking the variation of deformation and.bending with the
variation of theforces and moments is the most simple.
The conditions are discussed under.which the
calculation of the stability of two-layered shells can,'
with previously.given error, be reduced to the
calculation.for.single-layered,anisotropic elastic shells.~
In discussing the.physical.relations onthe theory of,
deformation, the case of an incompressible material is
Card 1/3 considered first. In the expressions for the variations

ABSTRACT: Thin elastic orthotropic flat shells not significantly differing from
spherical shells are considered. The equations of theirdynamics are recorded
on the basis of an analogy with the free oscillations of an anisotropic flat plate-:
In determining the frequencies only boundary conditions for deflection are solved.
A solution is also obtained for theAnverse problem: the rigidity, charact eiristic s
of shell are determined for a given frequency of free oscillations. [Translation
