Осесимметричная задача нестационарного вдавливания затупленного жесткого тела в поверхность упругого слоя

Abstract

Nonstationary indentation is studied for a blunted rigid body affecting the elastic layer. The general formulation of the problem includes different boundary conditions on the free surface and the contact region of the layer. A simplified nonmixed problem that is valid during early times and can serve as a rateable one for the later period is solved exactly. The solution is compared with the plane case.
