PERIODICAL: Tr. Gor1kovsk. inzh.-stroit. in-ta, 1956, Tir 25, pp 28-43
ABSTRACT:
Card 1/1
Fitting Stresses are determined by the methods of two-dimensional
elasticity theory, utilizing the work of D. I. Sherman (Dokl. AN SSSR,
1940, 27, Nrg ). The press-fitted parts are assumed to be solid cylin-
drical washt:rs and the fitting pressure is assumed to be uniformly
distributed along their circumference. The outer contours of the parts
are assumed to be defined by curves characterized by the property
that, within the area circumscribed by such curves, a circle with unit
radius may be conformally represented by means of a polynomial
expression of the n-th power. The problem, then, is reduced to the
solution of a system of linear equations. The results of numerical
calculations are adduced, and approximate formulas are provided.

ABSTRACTt The author proposes a method for the numerical solution of the
problem on the strained state of a composite isotropic medium,
using the Muskheliahvili (1) method and the experimental-
analytical method of conformal transformations (4).
The conformal mapping function in the form of a polynomial is
constructed with the aid of electric analogs. The function
represents an approximate conformal transformation of the unit
circle to the given region. This makes It possible to obtAin
then by the Muskhelishvili method the rigorous solution of this
Card 1/2 elasticity problem for a region which is very close to that

TEXT, The problem frequently arises of establishing a
correspondence between the points of the unit circle and the
points of the boundary of some semi-infinite domain S. To do
this it is convenient to transform the domain S with boundary L 0
into an enclosed simply-connected domain 31 with boundary Ll by
an inversions It then remains to find the transformation between
S, and the unit circle, The establishment of a correspondence
between points on the boundary of the circle and those of Ll, and
the construction of a polynqmial giving the conformal mapping of
the circle on to a domain Sj which is very close to the domain Sl,
can be achieved with the aid of electrical simulation (Ref. 2).
However, the function effecting the mapping of the unit circle on
to S' (which is very close to S) can be simplified by the

observation that in two-dimensional problems in the theory of
elasticity (where the problem under discussion arises most *
frequently), the boundary Lo assumes the particular shape that the
ends which tend to infinity do so in directions parallel to the
real axis. Thus the t ansformation consists of the sum of a term
of the form C-1/(l + and a power series int (f is t1j.
complex variable in the plane of the unit circle). The effic-
ients of the power series are obtained by putting 114.1 = e
expressing the coefficients as OLk + iOk, and separating the real
and imaginary parts. The results of a simple application of the
theory are given. There are 2 figures and 4 Soviet references,

gives two infinite systems of linear algebraic equations, which to~

known, it is possible to use a finite number N of terms of the se-

TEXT: In solving harmonic and biharmonic problems of the plane theory of
elasticity by methods based on the application of Cauchy-type integrals and con-
formal mapping, it is necessary to know the functi6n which maps the unit circle
onto the (simply connected) region occupied by the-elastic medium. Here a parti-
cularly simple and effective solution of biharmonle problems is obtained (as was
demonstrated by N.I. Muskhelishvili) when the mapping function is a polynomial.
In 1955, the author had proposed (Ukrainskiy matematicheskiy zhurnal, 1955, v. 7,
no. 2, 3) a method of approximate construction of a mapping function W (~ ) in
the form of a polynomial. An approximating polynomial w n (~ ) of degree n is
constructed according to the Schwartz formula with the aid of a trigonometric in-

The method of solving problems In the theory of elasticity under the condition
that the mapping function is a polynomial Is illustrated upon the problem of the
deflection of solid rods (the harmonic case) and on the plane problem for a sim-
ply connected region with specified concentrated forces and moments (the bihar-
monic case).
