CONTACT INTERACTION OF A CIRCULAR PUNCH WITH A PRELIMINARILY STRESSED ISOTROPIC LAYER

摘要

Using the linearized elasticity theory, we obtained the solution of the contact problem of pressure of a rigid circular punch of complex geometry on a preliminarily stressed isotropic layer. A numerical example of constructing the distribution function of contact stresses is considered. The effects of residual strains in the layer and the shape of a rigid punch on the distribution of contact stresses are analyzed.
