Compression of prestressed isotropic layer by two coaxial circular stamps.

Abstract

The solving of tasks on the contact interaction of two annular punches and isotropic layer with residual deformations is built. Numerical example of searching components of contact strain under the punch is considered. The effect of parameters of the field of residual deformations and form of punch on distributing contact stresses tensions is analyzed.
