In this paper, the elastic-perfectly plastic antiplane problem of a crack in anisotropic plane of finite width is studied. Using the methods of Rice and Lekhnitskii, an exact solution in closed form is obtained.
A finite strain elastic-plastic finite element analysis is performed on a crack which lies on an interface between two dissimilar materials. The materials above and below the interface are assumed to be different from each other in yield stress or in strain-hardening exponent. Gurson's constitutive
Two-dimensional linear elastic fracture mechanics analysis of the opening-mode crack problem is carried out, in order to use a localized finite element method. The stress distribution near the crack-tip is stated in the form of eigensolutions obtained by a classical separation variables technique.
