Analysis of Stress on Interface Crack of Orthotropic and Isotropic Bi-Materials

Jun Lin Li, Shao Qin Zhang, Wei Yang Yang, Jing Zhao

Abstract

This paper is concerned in semi-infinite interface crack of orthotropic and isotropic bi-materials and using the composite material fracture complex function method. By means of constructing special stress functions with two real singularity index and solving the problem of a class of generalized bi-harmonic equations , the stress and displacement fields of two dissimilar materials are obtained .Results demonstrate that the stress and displacement fields near the crack tip show mixed crack characteristics without oscillation.
