Abstract
The solutions of contact problems on a soft or rigid coating of an elastic half-plane are of great practical interest. Accordingly, the present paper is divided into two parts: in the first part, we consider the problem of interaction between a rigid biquadratic die and an elastic half-plane through a thin soft coating; in the second part, we consider the problem of interaction between a rigid plane die and an elastic half-plane through a thin rigid coating. We derive integral equations for the problems under study and construct their approximate solutions by a regular asymptotic method. Earlier, the question of studying such problems was posed, for example, in [1–3]. Here we use these results to a large extent.
