Fracture Analysis of Semi-Infinite Interface Crack between Two Dissimilar Orthotropic Composite Materials

Jun Lin Li, Shao Qin Zhang

Abstract

The problem of orthotropic bi-materials semi-infinite interfacial crack was studied, by constructing new stress functions and using composite complex functions methods of material fracture on plane. It overcame oscillation singularity of stress and existing theoretical solution. When secular equations’ discriminations are and , the theoretical solutions to the stress fields and the displacements fields of semi-infinite interface crack between two dissimilar orthotropic composite materials near the crack tip are obtained.
