TITLEt High-temperature Induction Furnace of Industrial
Frequency for Brazing,?f Components
PERIODICAL: Promyslh-lenpaya energetika, 1960, No. 10,
pp. 15 - 16
TEXTt The authors propose & now design of on induction type
furnace Qperating at the supply frequency with a permanent
hermetically closed muffle and not an expendable one. The
furnace formq.a coreless transformer, the primary winding of
which is a-mixiltitui-k'solenoid (inductor) and the secondary
winding is the'hermetic muffle made of a refractory metal.
On connecting the inductor to an AC supply, currents are
induced in the muffle and partly also in the components inside
It which generate the required brazing heat. The temperature
control is effected by means of a potentiometer on the basis
of temperature values derived from thermocouples fitted
inside the furnace. The furnace consists of the following
basic parts: housing - 1; inductor - 2; thermal insulation - 3;
hermetic muffle lid - 5 and the magnetic circuit - 6.

High-temperature Induction Furnace of Industrial Frequency for
Brazing of Components d
The housing is made of ordinary "steel 511 and its dimensions
are 1 000 x 1 000 nn. To prevent heating of the housing
separation gaps are provided. The inductor is a two-layer one
and has 78 turns of a 16 x 16 mm hollow aluminium conductor.
The outeir layer has 5 tappings, enabling selection of the
necessary thermal regime of the furnace. The dimensions of
the inductor are: external diameter 823 mmi internal
diameter 785 mm and height 750 mm. The thermal insulation is
made of "ultra-lightweight'l material (between the internal
layer and the external surface of the muffle) and f
_/irebrick.
The muffle is made of refractory )Maheet steel,
11 mm thick; the joints are fused by argon are welding., The
cover of the furnace is of nonmagnetic steel, 14 mm thick with
a pipe connection for fitting a vacuum pump, introducing a
gas flux and thermocoupleS. On the inside the lid is fitted with
thermal insulation. On the outside tt is water-cooled. The
furnace characteristics are as follows; power 65 W;
voltage 380 V; current consumption 180 A; current intensity

in the furnace 700 A; rating of the condenser bank 350 kVAr;
temperature 1 200 _ 1 250 OC. This furnace has the following
advantagess the power consumption is only one-quarter of
that of a chamber furnace; the process is much less laborious;
a great saving is obtained in expensive refractory metal for
manufacturing the muffles. The annual saving in electricity
amounts to 600 000 kVh. This proposal was awarded second
prize in the Fifteenth All-Union Competition for Saving
Energy. There is 1 figure,

Abstract : The author compares the two types of fundamental dependencies used
in the theory of plasticity. They are 1) equations of the theory of
elastic-plastic deformations which establish a connection between
components of deformation and components of stress and 2) equations
of the theory of plastic flow, which connect infinitely -small in-
crements of these components. The author presents some qualitative
indications that results obtained from the tvo different theories
will coincide closely in most cases.

ABSTRACT: Bending of curved thin walled tubes is accompanied by
flattening of their profile and as a result of that,their
flexibility increases sharply. A theoretical analysis of
this phenozenon was first carried out by Karman in 1911
and a number of authors have dealt with the problem in
more recent years. In earlier work of the author (6)
attempts were made to analyse bending of curved thin
walled tubes in the case of plastic deformations whereby
the solution is constructed on the basis of the principle
of minimum total energy; the difficulties caused by the
non-linearity of the problem were overcome on the basis
of the assumption that the relation between the intensities

the linear law. It was found that during plastic
deformations the flexibility of the tube increases only
slightly. In this paper the solution is based on a
different variational principle, the principle of mi
additional work; it is in this case possible to arrive at
a solution of the problem for cases when I'- BTmj whereby
B is a constant and m is an odd number larger than zero;
flexibility values for other magnitudes of m can be
obtained by interpolation. This approximation enables
establishment of the fact that the flexibility of the tube
increases sharply with increasing m. The given results
indicate that the flexibility coefficient b increases
sharply on transition into the region of plastic
deformations. This is attributed to the fact that
4Aattening causes reduction of the longitudinal deforms,
tion and a reduction in the stress 00 For balancing a
given bending moment, the required increase in a is
larger in the plastic range of deformations than in the
elastic one. The obtained solution can be directly

ABSTRACT: The results of various authors, for instance, of
Heal B. (Ref-5) relating to "Lhe determination of the
torsion resistance of an initlally bent rod prove
indirectly the usefulness of the plastic flow theory.
Therefore, the authors considered it of interestoto

here results are described of torsion experiments on
tubes which were first plastically deformed by internal
pressure. Inside a special set-up a vertically disposed
tube was fixed which was stressed by internal hydraulic
press-are, The measurement of the pressure was accurate
to a degree 0.35%. The change in the tube diameter
under the effect of internal pressure was recorded in
six points along the.q iircumference of the tube-with an
indicator having scale ions of I It. The torsion was
effected by loads appli!"Np~rms of 1 m length. Seven

follows from the theory of plastic flow; thereby, the
degree of plastic deformation caused by the internal
pressure does not manifest itself greatly on the values
of the shear modulus and torsion. The coefficient of
proportionality between the torque and the twist angle
is strongly dependent on the magnitude of accumulated
deformation; these conclusions of the theory of elastic-
plastic deformations contradict the above mentioned
experimental data.

ABSTRACT: Recently Hoff (Ref.1) defined tho rupture time of a
bar in tension as the time at which the cross-sectional
area of the bar vanished as a result of unbounded quasi-
viscous flow. Kats (Ref.2) has studied by the saiaie
method the strenSth of thick-walled pipes under an
internal pressure. The rupture time of a rotatin,-, disc
,.jith a hole bas been calculated by Rosenbloom (Ref.3).
In this Ejnpei- the author describes an attempt at defininL;
the i~upture time takinB account of embrittlemexit. The
effect of stresu concentration has been evaluated bv means
of the analysis described. If at a Given temperature the
material can undergo considerable deformation, the stress
distribution is noticeably evened out and hence the
effect of a stress concentration on the strength of the
material is weakened. Conversely, for small deformations
Card 1/2 the sensitivity of the material to stress concentration
On the Rupture Time in Creep Conditions SOV/24-53-3-5/37
is increased. It is also pcssible to make a comparatively
simple approach to the definition of the rupture tine
and the conclusioLs generally agree with the observations.
In some cases (for instance, inside an a,~gressive medium)
a preferential formation of cracks emanating from the
surface of the body was observed; for such cases the time
to failure can be determined according to the method
described in the paper provided it is supplemented by an
equation which determines the speed of failure along, the
norma-2 to the surface. The author expresses his thanks
to I. G. Sobolev and Ya. B. Fridman for their useful
advice.

TEXT: The paper in a continuation of previous work (Ref.2).
The well known Prandtl solution (see e.g. Ref.1) of the problem
of the flow of an ideally plastic layer compressed by rough, rigid
plates forms the basis of a number of methods for the approximate
calculation of the compression of a plastic layer. The present
note derives a solution of the creep problem for a thin layer
compressed by rigid rough plates at sufficiently high pressures.
Under plane deformation conditions the deformation velocity
4z = 0 and the flow occurs in the xy plane; the layer occupies
the region x > 0, (yj 0 hol.ds. If ~..the
condition just given holds, the system (4) may always be brought to the
dc 1 2'T
normal form :a - - - [B ( t )?A'- + ,dT (1-192,.*'.) (7), where
dt & k= 1, 2,A 2Ck 14T*3.Ckdt
Aik is the*algebraic complement of the corresponding element of the deter-
minant A. If the solution of the variation equation O'is set up in
the iorm (3), tAe values"C-1, a 0'. (1 is 1,2,.o.) correspond to the
exact solution,:and here 0, 0 &C > 0 (9) holds.

System (9) is best-numerically or graphically solved by means of the
Euler method. The method discussed may easily be applied to relaxation
problems, mixed problems, to non-uniformly heated bodies, to case3 with
lacking similarity of creep curves, and to elastic-plastic deformations.

TITLE: On the stressed state of a plastic filling
PERIODICAL: Akademiya nauk SSSR. Uvestiya. Otdeleniye

no-5, 1962, 63-67
TEXT: The problem of the tension 9f. an axisymmetric filling
was studied in earlier work'of the author. In this paper the flow
of a plastic filling in conditions of plane deformation under
tension (and compression) and the problem of str'engthening are
considered. The filling is assumed to be'thin and joining two
sufficiently rigid parts which have approximately the same moduli
of elasticity as the filler, but considerably higher yield point
values. If a moderate force is applied per unit length
perpendicular to the sandwich construction, all the joints will
suffer elastic deformation. It is assumed that the surfaces of
contact between the filling ahd the outer layers remain plane.
An approximate solution is sought for the stress on the surface of
the filling. An expression is derived relating the mean stress p

to the parameter C VII (6
2 v'(b)
where v is the displacement'in the axial direction and 6 is
the ratio of the thickness of the filling to its width. For
C 0, corresponding to the onset of plastic flow, p = 2k (k
yield point). For small C the tangential stress distribution
is nearly linear. As C tends to infinity the tangential stress
tends to the constant value k. This corresponds to the boundary
conditions of the layer for which the Prandtl solutions were
obtained. For C --~ oD the derived formulae yield the well known
Prandtl equations. The normal stress component has a maximum
value on the axis of the filling. The relation between this
maximum value and p is depicted graphically. To examine the
effect of strengthening the material it is assumed that for
tangential stresses T _< k the material is elastic but that for
T > k a linear strengthening applies, i.e. for T-< k, T = GT'
and for T ',>_,k, T = A + Br, where r in the intensity of the
shear deivrmation and Q is the shear modulu*. The resulting

changes in the various expressions previously derived are
considered. As B tends to G, C tends to zero. An C tends to
C' = (G/B - 1) 65, p/2k tends to infinity. With mtrengthening
there is no limiting loadj the quantity p/2k being bounded only
by the strength.
