Abstract

Description is given of a complex variable-variational method to investigate the stress intensity factor associated with the mode II cracking. In this work, a cracked plate is decomposed into two subregions with edge cracks. According to the theory of anisotropic elasticity the stress and displacement series which satisfy all basic equations and stress-free boundary conditions on crack surfaces are established. It is based on a generalized variational principle about multi-regions to satisfy the remaining boundary and interface conditions. Numerical studies have revealed that the convergent results are given by a quite simple program which reduces data manipulation and computer time.
