โฆ Synopsis
Let a circular flat punch penetrate a finitely thick slab resting on a rigid foundation. Lebedev and Ufliand showed that the determination of the stresses and displacements can be reduced to solving the Fredholm integral equation
We show how to reduce this integral equation to a Cauchy system in which ,~. plays the role of the time-like variable. Numerical experiments show the computational efficacy;
Man lasse einen flachen, kreisrunden Durchschlag in eine auf einer steifen Unterlage ruhenden Platte yon endlicher Dicke eindringen. Lebedeff und Ufliand haben gezeigt wie das Bestimmen der Drticke und Verschiebungen zuriickgefiihrt werden kann auf die Losung der Integralgleichung yon Fredholm, u(t) = 0 ( t ) + 2 k(t, y, 2)u(y)dy, 0 <. t.<~ 1.
Wir zeigen, wie man dieses Problem auf ein Cauchysystem reduziert, worin der Parameter t die Rolle der Zeit spielt. Ein numerisches Beispiel illustriert die digitale L6sbarkeit.

A boundary integral equation algorithm for the contact analysis of elastic beams is presented in this paper. The analysis of this sort is complicated by the unknown and moving boundary points. The new algorithm incorporates the interface compatibility equation, derived from the principle of minimum
A typical integral equation, which arises when solving linear plane contact problems for semi-bounded bodies, is considered. By using a special representation of the kernel of this equation, an approximate method is developed for solving it that is effective over a wide range of variation of the dim
lt is shown that a modification of the integral equation formulation [I] can be used to find an expression of the unbounded contact stress of problems in the theory of elasticity. The modifications consist in reducing the problem to a Hilbert-type singular integral equation rather than that of the C
It is shown that the coupled singular integral equations with trigonometric kernels appearing in the problem of adhesive contact between an elastic circular cylinder and two identical rigid compressive rollers may be reduced to a problem of Muskhelishvili type and may be explicitly solved. The solut
