WEAR OF ELASTIC FOUNDATION WITH COATING BY SYSTEM OF RIGID PUNCHES

Abstract

This article is devoted to the study of the wear problem of elastic layer with nonuniform coating by the system of plane rigid punches. It is assumed that punches has different lengths. A mathematical model of the problem is obtained. It is a system of mixed integral equations (with Volterra and Fredholm operators) with additional conditions. The analytical solution of the problem is presented. In the solution coating nonuniformity is represented by separate factor. It allows one to make calculations with high accuracy even if coating nonuniformity is described by rapidly changing function.
