โœฆ Synopsis

The paper is concerned with a Fredholm integral equation of the first kind arising in contact problems for elastic foundations with voids. In the structure of its kernel there are two principal parameters. The first one is of a relative thickness of the strip foundation. The second one is coupled with the porosity of the material. We study uniqueness and solvability of the main integral equation, and then give explicit analytical asymptotics for the leading asymptotic term of the strip compliance, in the two limiting cases of thick and thin strip. Finally, analytical results are compared with results obtained by direct numerical treatment.

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.

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 wh
