Abstract

By using the generalized complex variable function method,complex representations of the components of stress and boundary conditions of the plane elasticity problem of plate of orthotropic composite material are given.By constructing the appropriate generalized conformal mapping,the analytic solution of the stress field and the stress intensity factors at the crack tip of the plane elasticity problem of plate of orthotropic composite material with semi-infinite crack is obtained.
