Influence of hardening of a material on the stressed state of an elastoplastic shell with internal crack

Abstract

The problem of determination of the stressed state of an elastoplastic isotropic shell of arbitrary curvature with an internal crack is considered with regard for hardening of a material. We obtain a system of singular integral equations and solve it numerically by the method of mechanical quadratures. We investigate the influence of hardening of a material on the basic characteristics of the stressed state.
