TITLE R&ylGjgh_typeWv6B on Cylindrical Surfaces (Volny tipa relayewkikh

PERIODIC&L, Altusticheskiy Zhurnal, 1958, Vol IV, Nr 2, pp 131-136 (USSR)
ABSTRACTs It was found experimentally (Ref 2) that Rayleigh waves may be
propagated on cylindrical aurfac#~s and they may pass, practically
unreflected, through curvatures with a radius of the order of
one or more wavelength. The present paoer deals with waves
propagated along the sarface of an infinite eirculAr cylinder and
along the surfaze of a cylindrical cavity of circular cross section
in an infinite elastic medium. In both cases keonvex and concave
cylindrical surfaces) the author limits himself to a two-dimensional
problem in cylindrical coordinates r, 0, z (Fig 1), when the
field in the elastic medium does not depend on z. It is also
assumed that only steady-state harmonic vibrations are present. The
analogue of Rayleigh waves in this case would be such a solution of
the elastic theory equations which would have the following
properties% (1; it should satisfy the conditiou of absence of
,/stresses on the cylindrical surface; (2) the solution should depend

on the angular coordinate e in the form 9'*iP$, whero p is a certain
non-dimensional quantity which may be called the angalar wave-number;
k3) Li the radius of curvature of the cylindrical surface tenis to
infinity but the ratio p/R, where R Is the cylindsr radius, rwuainj
finite the solution should become an ordinary Rayleigh wave proparat,3d
along the plane boundary between an elast1c sami-infirits space and
vacuum. The treatment Is not limited to integral values of p and
for the solid cylinder the author makes the solution obey the
condition thqt it should be finite on the cylinder axis - For the
convex cylindrical surface the author finds the following expression
for the phase velocity of the surface wavess C - CO(l 1, 6))whore
Co is the phase velocity of Rayleigh waves along the plane boundary
of an elastic semi-space and vacuum, and d is a small Lorrection
-which depends on the elastic properties of the medium and on p.
For the concave cylindrical surface the phase velocity is given
by C = Co(l + J),,where 3 is a small correction which depends on the
elastic properties o' the madium and on the value of klR, where kl
is the real part of the complex wave-number k. The author thankz

,'.3SV1,ACT-. This work experizentally examines the influence of single
surface imperfections. Here the author use3 various models
of nurface imperfections and he studies the reflection of
RayleiL;h waves on these models. The author chose the followirij,
nodels of imperfections: A slit, cut into the surface; a
semicylindric clearance; a wedge with various generating angles.,
The first two models cover the defects of the type of slits
and buli-es, and by the third mentioned model, the Jogs in
the surface can be described. The slit, the cylindric clearance.-.,
and the ed6e of the wedge are assumed to be vertical to the
propagation direction of the Rayleigh wave. The measurements
were performed with impulses with a frequency of 3 megacycles
waves
and the pulse duration was lo microseconds. The Rayleij

were produced at plane side faces of rectangular metallic
bars. The results of the measurements are illustrated in
3 diagrams. A strict interpretation of the here obtained de-
pqndences demands the solution of the diffraction of Raylei,,,h
waves at a w3dge, at a alit, and at a semicylindrical bui:-e.
Because of tie extremely difficult solution of these probiellis
the author restricts himself upon giving some experimental
facts and upon the explanation of some particularities of the
here obtained curvau. A part of tl~o energy of the incident
Rayleigh wave always transforms into th6 energy of longitudii'L1
and transversal waves, which are dispersed by the na.,-,ed 17,-,-
perfections. 'Slits and clearances with the radius R> 0,25 k
disperse the stroniest. The curves for the dependence of t.-.e
reflection coefficients and of the pausage coeffici4entn on
the an(-,le of incidence have some sharply marked maxima ar-!
minima, whereby as a rule the maximum of the reflection
Ca--d 2/4 ooefficient corresponds with the minimum of the passaje

coefficient and vice versa (except the case 0 a 1150). The
reflz-ltion coefficients and the passage coefficients never
reach the values 1 and 0. On occasion of approximation of
the wedj;e angle to 18oO the reflection coefficient goes
toward zero and the passage coefficient toward 1. The resultr
found here, seem to prove to be correct for all elastic wedges.
In the -ase of an increase of the ratio hfi'.(whereby h dendes
the slit depth) the reflection coefficient oscillatingly in-
creases and the passage coefficient oscillatingl~ decreases.
Also the curves for the semicylindric clearance are illustrated
by a diai;ran,. In the case of equal depth of the slit and of the
clearance a slit screens out more and also reflects stronger
than the clearance. Finally the author thanks G. D. Malyuzhinets

shows tMt the usual Rayleigh wave is hot propagated in a plane-parallel
elastic layer which has a source of si=siudsl Rayleigh waves placed on
one of its free surfaces. When the layer thickness 4 is sufficiently
great (d > 2XR, vhere XR is the Rayleigh vavelongth in the layer) two
normal waves are excited. They are a zero-symmetrical and zero-
antisymmetrical waves, known as no" and 0a" waves respectively. These
,waves are similar to Rayleigh waves in the.case when d > 21R, e.g. their
phase and group velocities are close to the phase velocity of Rayleigh

difference it close to zero, their total acoustic 51eld is similar to
the acoustic field of Rayleigh waves and cousequently -the "s" and "a"
waves together are called a quasi-Rayleigh wave. The theoretical
deductions were checked erperimentally using a generator of square
pulses of 2-10 lisec duration, 2.7 Mo I/a frequenny,avedge-shaped radiator
and receiver of Rayleigh waves (Ref 2), a resonance amplifier and an
indicator. The experiments were carried out on duralumin strips of
0. 9-5 mm thickness and confirmed the theoretical predictions -

TEM. In ultrasonic de.fectoscopy, Rayleigh waves are usdd, and therefore
Iinterest is displayed in the peculiar featuras of the propagation of Rayleig4
waves over cylindrical surfaces. In his earlier papers, tiie author was al-
ready able to show that hr,.rmonic elastic surface waves, propagating over a
free surface of an InTinitely long cir2ular cylinder or a circular cavity in'
an unbounded elastic mediumj are similar to Rayleigh waves, and go over into
20 the latter at koR co, if the propaGation direction is perpendicular to
the surface. ko is.the wave number of the Rayleit;h waves, R the curvature
radius of the surfaces. Therefore, the author is able to confine himself,
in future to concave and convex surfaces on Rayleleh waves when studyin&r
then holds for a convex
wave propagation. For the phase velocities, C> Cc
surface, and C 100, was experimentally studied by the
author. Investigations were carried out by using square pulses filled up
with sinusoidal oscillations by means of a Rayleigh-wave emitter and receiV4
er, a resonance amplifier, and an indicator. The experimental values of 6

TITLE: Normal waves In a solid cylindrical layer
PERIODIOAL: Akusticheekly shurnall v& 9f no* ip 1963, 19-22
TEXT: The propagation of harmonic plane waves through a thin layer of
hollow-cylinder shape perpendicular to the cylinder generatrix is studied
under the assumption that the elastic Afield does not depend on the z
coordinate. The solution of the equation of elasticity has to satisfy the
following conditions: (1) Absence of tensions in the inner and in the outer
cylinder surfaces; (2) The solution depends on 0 according to exp(�ipQ)'
where p is the wave number; (3) If the radius of curvature tends to infinityp
h and a) become characteristics of normal waves in a plans layer. Under
these assumptions the front of the propagating normal waves Is a plane which.
propagates along the cylinder axis. The solutions

ABSTRACT: 11--author describes the first experiments on them servation of inter-
action between ultrasonic ayle gh waves and conduction e1 c rons in CdS, inasmuch
as such an interaction was not observed in the past. The experiments were made in
the pulsed mode using apparatus consisting of en electric square-wave pulse genera-
tor with sinusoidal carrier, a resonant amplifier, and a cathode ray oscilloscope.
,The pulse duration was 6 pace and the carrier frequency 30 Men. Ilie crystal was
grown from the melt under inert-gas pressure and measured 11 x 11 x 50 mm. The
Rayleigh waves were propagated on the 3-1 x 50 mm fac2, the surface of which was
polished. The excitation and reception of the waves was with the aid of ridge-type
.converters described by the author earlier (Akust. zh. V. 7, 295, 1961). The inter-

action between the Rayleigh wave and the conduction electrons was estimated by de-
termining the coefficient m of additional wave damping brought about by the conduc-
tion electrons. The dependence of m on the specilic conductivity a of the crystal
was determined for this purpose. The results show that the damping of the Rayleigh
wave, and consequently its interaction with the conduction electron, depends very
strongly on the conctictivity of the crystal, and increases particularly rapidly with
increasing conductivity when 10-8 < a < 1-7 x 3D-5, A maximum interaction with the
electrons occurs between 6.9 X 10-4 and 1.7 x 3D-5, where the damping was so strong
that the amplitude of the Rayleigh wave could not ba measured. For a > 6.9 X 10-4
the damping decreased rapidly with increasing conductivity. The author thanks A. F.,
Dorokhov for preparing the ridge structure for the excitation and Teception of the
Rayleigh wave., and L. D. Rozenberg and A. A. Chaban for valuable discussions. Orig.

ABSTRACT: The direct amplification of transverse and dilatational ultrasonic waves by means
of a static electric field (drift field) has been observed many times. Some authors have also
described the use of CdS crystals for the excitation and reception of lif ultrasonic waves. If
a high-resistalice barrier or diffusion layer is formed on the surface of a CdS crysW; when
electric current is fed to the crystal, most of It remains in the surface layer instead of pene-
t-Lating into the bulk of the crystal. This circumstance Is, apparently, the main factor which
makes difficult the generation and subsequcnt amplification of a drift field of ultrasonic waves
in a CdS crystal, and why this effect has not been obser-d heretofore. In order to create a
drift- field of the required magnitude in the crystal it is necessary to use very high voltages.
The present autbors made an attempt to achieve the generation and amplification of trwsverse
ultrasonic waves in a CdS crystal. The experiments showed that a signal observed (C) proved
Card 1/2 UDC,1534-16

L 303834)6
ACC NR- A-P6007992
to be an ultrasonic pulse of transverse waves generated and amplified in the crystal. The geneer-
ation of C is achieved by the forward front of the pulse of the drift field due to the presence of
a barrier layer in the crystal. The authors conclude that both generation and amplification of
ultrasonic wavos are indeed feasible In a CdS crystal. A quantitative anAysis of the results
observed is given, together with detailed descriptions of tho procedures tuid the equipment used.
In conclusion, the authors express their sincere gratitude to L. A. Sysoyev for making avail-
dis-
able the cadmium sulfide single crystals and to A. A. Chaban for valuable advice and a
cussion of the work. Or1g. art. has: 4 figures.
