TEXTs Based on the experience of the Khar I kov' S orp,i molot"jiPlant,
the Vladimirov Tractor Plant started the casting of'orajakshafts for the
DV30 engine. The authors enumerate the defioienoies oactirring during the
casting of the crankshaft for the 6MA7 (SMD,7) engine at;' the. "Serp i molottl
Plant and point out that the elimination of black spots by Increasing the
machining tolerances is not expedient; therefore, it is n:ecessary to pre
vent the origination of black spots which can be attained by the desulfuri
zation of the cast iron, bringing the $content down to 0.008  0.005%.
This is possible if the cast iron is smelted in a bdaio electric furnace.
AttemptB were made to eliminate the technical difficulties connected with the

production of magnesiummodified cast iron by using other modifiers,1ikez'
cerium, tellurium, oalcium, strontium, lithium, etc. Tests proved oel~ium'
and foundry alloys on the base of cerium to be the most suitable modifiers,
In comparison with magnesium, cerium offers the following advantagess~no
metal ejection during modification; the assimilability of cerium amounts:to
not less than 30%; lower sensitivity of the cast iron to demodifiers; in
significant cast iron temperature drop during the modification process (be
tween 20 and 4000; uniform distribution of sulfur over the casting and tLb
sence of black spots on its surface. In order to maintaina constant;ohem
ical cast iron composition during the investigations basic cast iron of the
following chemical composition (in %) wag smelted in a 3tdn acid electric
furnaoet 3.5  36 C; 2.0  2.2 Si; 0.8  1.0 Mn; knot more than M4 S.
Then this cast iron was remelted in a 50kg capacity Iacid induction furnace.
The metal was heated to 1,480  1,4500C, the modifiers (compositiont 5  7%
Mg, lWo Fe, 40  50~6 Ce, the rest rare earths) amounting to 0.4  035~0 of
the liquid metal weight was put on the ladle bottom.. To remove cementite'
formations and increase the mechanical properties, the cast iron Was subje.0i.
ed to additional modification by 03  040/6 CH (Si) 75 fer�ouilicium.. After
two minutes holding in the ladle the metal was poured into the crankshaft

microstructure and the mechanical properties. Table 1 shows the results
obtained. The sandresin mixture was prepared In a miier of NIILITMASh de~
sign, model 821, the shell mold was made on a model 83P machine of KItITME2
design. The cast crankshaft structure contained ledeburite'oementite.' The
crankshafts were annealed as to the following conditio~st holding at 9500C
for 2  5 hours, cooling in the furnace to 6300C, holding at 6300C fOr~l
hour, cooling in the furnace to 4500C, further cooling.in the air. in;com

Title : Remarks on S. S. Grigoryan's article "Stating of,dynamic problems
for ideal plastic media"
Periodical Prikl. mat. i mekh., 19) NovDec 1955, 733
Abstract The present authors remark that S. S. Grigoryan carried out'interesting
investigations of the equation of state of.plastic medium, wh~ich~
equation was proposed by them ("Dynamics of~grounii masses," DAN,SSSR,
95, No 4, 1954), and his results deserve atiention. Grigorya.h pointed
out that the energy condition on the surface of strong discontinuity
is fulfilled during the entire time of the process only if in'the.
external region the pressure equals the critical pressure, as~was
assumed in the authors' work, and he also made a conclusion cbncer'ning
the impossibility ofthe existence of a certain zone III etc., As;,a
result Grigoryan concludes categorically that the:stated problem can
not be solved by.means of the authors' equation of state. The present
authors cannot agree with the categorical character of this conclusion.
The authors consider their scheme as a limiting scheme and not as'com
pletely solving the problem of deformation of densification of grounds.
The entire problem consists in whether their description gives the main
outlines of the phenomenon of dynamic densification of grounds'. The
problem remains open.

ABSTRACT The authors examine problems. relating to the emission and pro
pagation of quasiharmonic stationary. elastic wavez under conditions
obtaining in underground mines. For the purposes of their examina
tion of these problems the medium is considered to be ideally' horno
geneous. They examine two types of driving forces: 1) Forces actin g
from within the elastic medium [ three dime ns ion:al (spherical; Transl.
Ed. Note)] waves and Z) forces acting on them free boundary of a semi
infinite medium (surface waves). It is ~esta6tished that the driving
power needed to excite surface waves having a given amplitude is ap
proximately two orders of magnitude smaller than the driving power

Also, the authors elucidate the law whereby the intensity,;of the' emissive powe:r must
increase with the observer' s distance from the emitter. An account is given of ob
servation methods used ,and the results obtained thereby!, in coal mines of the Don
bass. While, in general, the author's experimental findings do support their theo
retical conclusions, the wave  ~ttenuatlon picture as traced by1hem is rendered more
complicated in some respects by the operation of interference and resonance factors.
Included are experimental data on the propagation distance of elastic waves (in the
3001, 000 cps frequency range) in Donbass coal seams and inthe rock enclosi Ing
them.

ABSTRACT: In 1933 Smirnov, V. and Sobolev, S~ (Re.f.1) published
a paper (in French) in which they mounded a new~method
of integration of the wave equation~6y means of the ~
functionalinvariant solution. In earlier work, them
author of this paper and Zaytsev, L.P. (Refs.2 and 3)
found that this method is very suitable for studying
the near front zone of the wave and1eads to physically
clear results but they studied only~very simple problems.
G. S. Markhasev, G.S. (Ref.4) also.6onsidered them ~
reflection and refraction of spherical waves on a plane
boundary of two elastic media; he developed a method
of separating the asymptotic part of theiwave field.
However, he did not consider important features of the
wave field and his final results arein a too general.

ABSTRACT: The problem was investigated in Ref A)of the reflection
and the refraction of sphbrical waves at~a plane boundary
between two elastic halfspaces. The solution of this pro
blem was derived by the method of functionally~ invariant ~
solutionsp and the possibility of approximately describing
~he reflected wave PP in the region of incidence was
indicated. In the present paper the author considers the
approximate description of the reflected wave, PS and the
direct waves in the region of incidence. . The statement of
the problemg the choice of a frame of reference and them
choice of symbols are as in Ref.(J). It'is assumed that
at a distance, z0 from the plane boundary division
there consists a point source of disturbance emitting a
sphericalf longitudinal wave. The source strength is

considers the adiabatic propagation o;f a s0heri cal wave

Several assumptions are made which thbauthor notes are
subject to empirical verification. Ftrat. the~wovk of

strip of finite width. The dynamic equations of elasticity theory are solved under
boundary value conditions corresponding to time with initial conditions zero. thi "
problem is shown to be reducible to the WienerHopf problem; (2) The problem of Iootion

TEXTs Based on the experience of the Khar I kov' S orp,i molot"jiPlant,
the Vladimirov Tractor Plant started the casting of'orajakshafts for the
DV30 engine. The authors enumerate the defioienoies oactirring during the
casting of the crankshaft for the 6MA7 (SMD,7) engine at;' the. "Serp i molottl
Plant and point out that the elimination of black spots by Increasing the
machining tolerances is not expedient; therefore, it is n:ecessary to pre
vent the origination of black spots which can be attained by the desulfuri
zation of the cast iron, bringing the $content down to 0.008  0.005%.
This is possible if the cast iron is smelted in a bdaio electric furnace.
AttemptB were made to eliminate the technical difficulties connected with the

production of magnesiummodified cast iron by using other modifiers,1ikez'
cerium, tellurium, oalcium, strontium, lithium, etc. Tests proved oel~ium'
and foundry alloys on the base of cerium to be the most suitable modifiers,
In comparison with magnesium, cerium offers the following advantagess~no
metal ejection during modification; the assimilability of cerium amounts:to
not less than 30%; lower sensitivity of the cast iron to demodifiers; in
significant cast iron temperature drop during the modification process (be
tween 20 and 4000; uniform distribution of sulfur over the casting and tLb
sence of black spots on its surface. In order to maintaina constant;ohem
ical cast iron composition during the investigations basic cast iron of the
following chemical composition (in %) wag smelted in a 3tdn acid electric
furnaoet 3.5  36 C; 2.0  2.2 Si; 0.8  1.0 Mn; knot more than M4 S.
Then this cast iron was remelted in a 50kg capacity Iacid induction furnace.
The metal was heated to 1,480  1,4500C, the modifiers (compositiont 5  7%
Mg, lWo Fe, 40  50~6 Ce, the rest rare earths) amounting to 0.4  035~0 of
the liquid metal weight was put on the ladle bottom.. To remove cementite'
formations and increase the mechanical properties, the cast iron Was subje.0i.

Title : Remarks on S. S. Grigoryan's article "Stating of,dynamic problems
for ideal plastic media"
Periodical Prikl. mat. i mekh., 19) NovDec 1955, 733
Abstract The present authors remark that S. S. Grigoryan carried out'interesting
investigations of the equation of state of.plastic medium, wh~ich~
equation was proposed by them ("Dynamics of~grounii masses," DAN,SSSR,
95, No 4, 1954), and his results deserve atiention. Grigorya.h pointed
out that the energy condition on the surface of strong discontinuity
is fulfilled during the entire time of the process only if in'the.
external region the pressure equals the critical pressure, as~was
assumed in the authors' work, and he also made a conclusion cbncer'ning
the impossibility ofthe existence of a certain zone III etc., As;,a
result Grigoryan concludes categorically that the:stated problem can
not be solved by.means of the authors' equation of state. The present
authors cannot agree with the categorical character of this conclusion.
The authors consider their scheme as a limiting scheme and not as'com
pletely solving the problem of deformation of densification of grounds.
The entire problem consists in whether their description gives the main
outlines of the phenomenon of dynamic densification of grounds'. The
problem remains open.

increase with the observer' s distance from the emitter. An account is given of ob

ABSTRACT: The problem was investigated in Ref A)of the reflection
and the refraction of sphbrical waves at~a plane boundary
between two elastic halfspaces. The solution of this pro
blem was derived by the method of functionally~ invariant ~
solutionsp and the possibility of approximately describing
~he reflected wave PP in the region of incidence was
indicated. In the present paper the author considers the
approximate description of the reflected wave, PS and the
direct waves in the region of incidence. . The statement of
the problemg the choice of a frame of reference and them
choice of symbols are as in Ref.(J). It'is assumed that
at a distance, z0 from the plane boundary division
there consists a point source of disturbance emitting a
sphericalf longitudinal wave. The source strength is

considers the adiabatic propagation o;f a s0heri cal wave

Several assumptions are made which thbauthor notes are
subject to empirical verification. Ftrat. the~wovk of

ABSTRACT: Three problems are studied., (1) That of waves fomed in an elastic medium
as a result of momentary disturbance of the continuum along an infinitely long plane
strip of finite width. The dynamic equations of elasticity theory are solved under
boundary value conditions corresponding to time with initial conditions zero. thi "
problem is shown to be reducible to the WienerHopf problem; (2) The problem of Iootion
under the action of a plane wave of a solid infinite strip in an elastic space. ~ This E

problem is a generalization of the problem of diffraction ~f a plane elastic wave on
a screen in the form of a strip. Parameters of motion of the strip are defined;to sa
tisfy the equations of motion; (3) The problem of the "transparent prism": two elas
tic (acoustic) media separated by an angular boundary. An effective method is pre
sented for computing the field diffraction for this problem. The authors thank! G. F.
