TITIAE: On the approximate calculation of reflected and refracted
waves. (0 priblizhennom vychislenii otrazhennykh

PERIODICAL: Izvestiya'Akademii Nauk SSSR*, Seriya Geofizicheskaya,
1957, No.7, *Pp. 841-854 (U.S.S.R.)
ABSTRACT: Asymptotic representation of sound and elastic waves were
considered by various authors who limited themselves
predominantly to the steady state oscillations and to the
propagation of waves with a discontinuity at the front.
Some authors (Refs.7-9) observed that in both cases
approximately the same law is obtained for the change of
intensity of the propagating wave. In this paper an
asymptotic expression is derived,forthe neighbourhood of
the wave front,for the intensity and shape of the
reflected and refracted waves which are suitable for any
curvilinear boundary and any shape of the incident wave.
From the mathematical point of view the here described
method is similar to the known method of studying dis-
continuities which propagate along characteristics; see
Card 1/ 5 Hadamard (Ref.12, Chapter 7) and Courant and Gilbert (Ref-13).
The fundamental idea of the method is as follows: the

solution is considered of a (p linear hyperbolic equation
of the secorml order as representing a propagating wave
and equalling zero before the wave front. If at the wave

equalling a , etc. n denotes differentiation along
the normal to the wave front), then in a point at a
distance d beyond the wave front, the solution can be
expressed by means of eq.(l), p.841. According to Courant
and Gilbert (13), the discontinuities are displaced along
rays and the magnitude of a discontinuity varies with
time and complies with an ordinary differential equation of
the first order. In para.1 the geometric magnitudes are
considered which characterise the movement of the wave and
formulae are. derived for the position of the front of the
propagating wave at any instant of time; the geometric
picture of reflection and refraction is dealt with in
pura.2. In para-3 the asymptotic representation of the
Card 2/ 5 solution of the wave equation in the neighboiirhood of the
front of the propagatinS wave is dealt with, investigating
tile change with time of the intensity of the 'propagating

7ave in the zone neighbouring the wave front; this
investigation was carried out by Hadamard (Ref.12) for the
more general asze when instead of eq.(2) any arbitrary
non-linear sec.ond order equation is considered. Para.4
deals with -t-lae asymptotic representation of the reflected
and the refracted waves and rules for the approximate
calculation of reflected and refracted waves in the near
front zone aro formulated; a numerical example is given in
para-5. The here described method allows an approximate
calculation of waves reflected and refracted at a plane or
curved interface to be carried out. If both media are
homogeneous amd isotropic, the angle of incidence is less
than the critical angle and the reflected rays do not
intersect in the region under consideration, the following
results apply and are derived in the present paper. In the
first approximation, the amplitude of the reflected wave is
equal to the amplitude of the incident wave at the point of
incidence, multiplied by the reflection coefficient for the
case of a plane wave at a plane interface, and by the square
Card 3/ 5 root of the ratio of the radii of curvature of the wave-
front of the reflected wave at the point of reflection and

waves. (Cont.)
the point of observation r4spectively. In the three
dimensional case, instead of the radius of curvature it is
necessary to take the product of the three principal radii
of curvature of the wavefront. It is possible to obtain
more accurate approximations for the reflected and refracted
waves but this involves computations which may be quite
extensive. If the incident wave is due to a source which
is active only during a short period of time, then the
described method will allow the calculation of the reflected
and refracted waves sufficiently accurately only if the
period of activity of the source multiplied by the velocity
of the waves, is less than the smallest of the radii of
curvature of all the considered waves. These radii must be
taken not only at the moment of observation but also at the
moment of reflection. For other waves the method is only
applicable in the region near the wavefront. The width of
Card 5 this region is of the order of the smallest radius of
curvature mentioned above, or of the order of the minimum
distance between the points on the wavefront at which the
intensities differ considerably (e.g. by a factor of 2 or 3).

to the establishment of the above mentioned definition of the solu-
tion. It is shown that a solution, defined that way, possesses many
properties of tho o:rdinary solutions of the differential equations
with continuous right hand. The possibility of obtaining criteria
for the existence oj! periodic solutions is shown. It is noted that
most of the criteria for the existence of periodic solutions of non-
linear oscillation oquatiohe St + f(t) + g(x) - e~t), remain correct
in the case of pieoq,wise continuous functions f(xlg(x), o(t), tco.
It is said that the application of the described methods allows the
proof of the existence of the solution for some problems of the op-
timal controls.

ABSTRACT: A method for solving the three-dimensional problem of diffraction of a wa
having an arbitrary form with a convex front propagating in a homogeneous medium by
dihedral and polyhedral anglesAs presented. Ray coordinates are used to solve the
problem and it is assumed that in the neighborhood of the domain of the front under
study, the solution of the wave equation can be expanded in a series

simple wave, that ishaving a solution of the wave equation such that the first term
of expansion (1) is the principal term is introduced. Various properties of simpli
waves are analyzed. It is proved that every wave with a convex front which can bl,

.With the aid of the Green's function, the solution of the problem of diffraction
any incident wave by dihedral or polyhedral angles is expressed in terms of a triple
integtal. A procedure for solving thLs integral is presented which consists in - X
representing each wave contained in the integrand by a sum of simple waves. The "'
obtained sum of simple waves represents the diffraction wave. The method presented

ABSTRACT: The autho ~ describe the manufacture of Ce02 melting crucibles
iby powder metallurgy4nd slip casting. Cerium dioxide* powder with rains
measuring 5-15-T ~in diameter was mixed with 6-8% binder based on paraffin
band 5% oleic acid. A steel mold was used which was prelubricatedl1with a. thin-
'layer of oleic acid. Pressing was done at a pressure of 200 kg-Fcm2. The
!crucible was then slowly heated for 10-12 hours to 12000C and final ainter-
;lng was done in a resistance furnace at 1500-16000C. Water suspensions of
I
,cerium dioxide were used for slip caBting. The slip had a pH of 4-5 and a
:moisture content of 58-60%. The suspension was allowed to stand for at
:least 24 hours before casting. After removal from the mold, the crucibles
were heated to 1700-175000 at a rate of 30-40 deg/hr and held at the final

tempe'rature for 6-0 hours. The apparent donsity"(Yolumetric weight) of the
:crucibles was 6.6-6.4 9/cm and the apparent porosity was less than 1%. A
-comparison of the calculated and residual cerium concentrations in alloys
malted in CeO2 and La20-A crucibles shows satisfactory retention of Ce in cerium
dioxide crucibles durin~g melting. Metallographic analysis of nickel-cerium alloys
.melted in CeO2 crucibles in a vacuum shows that the purity of the metal is
comparable to the purity of nickel melted-in alumina crucibles with hydrogen
treatment. Orig. art. has: 1 figure and 1 table. IJPRS; 36,7741

were effected with a pneumati-- hammer (fal21ng Weight 230 k9).
Specimens were haaipd in such a way that uniform temperatures were
obtained. Temperatures at the atort and end of forging were
chocked with an optical pyrometer. Various dies werim tested, the
ones adopted being swage dies with diameters decreasing from 40
to 30 to 20 mm In successive strokes,~ thiE was followed by the
use of a cramp to give a 15-mm diameter rod; final forging being
effected with flat dies. Best results were obtained with
variants where top-grade tungsten -was used, poorer grades giving
high oxygen and non-metallia inclusion contenTs. Regarding the
effect cf scrap content in the charge, variant IV gave a poorer
deformability and the authors recommend up to 50% scrap (up to
100% with vacuum vielting). It was found that replacement in the

impaired deformabillty. Strict adherence to the temperature
schedule during forging was found to be most important (confirming
the results of "he upsetting experiments). The influence of
temperature was reflected in the microstructures obtained. The
authors point out that a wider temperature range may be possible
with Larger specamens. impact strength and time to rupture at high
temperatures was also studied, tent pieces being prepared from the
forged rod which had been subjected to various heat treatments.
Impact strength (kgm/cm2) is shown as a. function of temperature in
Fig-5, the melting variant being marked for each curve. Fig.6
shows the time to rupture in hours (left-hand ordinate, shaded
areas marked with the variant number and with time to rupture in
hours), ~the non.-metallic inclusion content (5,~, middle ordinate,
curve 1), and the total 02 + N2 content. (%, right-hand line,
curve 2). The materials were tested at 8oo OC under a stress of
25 kg/mm2 on type PE-1 (YaB-1) and ~[1 -8 (VP.-8) machines. No
substantial differences in structure or fracture were observed,
The only differences being in the number of non-mctallic inclus ions
and grain size. High.-temperature strength was greatly decreased

APSTRACT: The investigation was performed with the aid of the experimental setup used by
N. Ya. Stomakhin, (Candidal~ degree dissertation, MoscowInstitute of Steel and An

Six discrete melts of Ce-tfeated Ni (refined electrolyti i at least 99. 9 87% pae, I illoyed
with 99.2% pure Ce) were inelted at 15500C (18230K) in identLeal CeO eLveibles (used in order
2
to reduce to a minimum the interaction between the Ce of the metal 7md, ihe crucible). The time
I. I :
needed for the equilibrium to set In (10-20 min) was the longer the hig the Ce content of the
alloy was. All the six melta were brought under the same temperatu pressure (298%,
760 mm Hg) in order to assure the reproducibility of findiq;s and subjected to tests for deter-
irninin the Solubffity of nitrogen in these melts by the method described in Stomakhin's work. 1
