Fully Plastic Crack in an Infinite Body under Anti-Plane Shear.

摘要

The problem of a semi-infinite body with an edge crack subjected to far out-of-plane shear is solved by a transformation to a hodograph plane and the Wiener-Hopf technique. The material stress-strain behavior is governed by a pure power hardening relation and the results are valid for both deformation theory and flow theory of plasticity. Results are presented for crack opening displacement,path independent J integral,and crack tip singularities for all finite values of the power hardening parameter. (Author)
