Abstract

A novel approach to suppress complex singularity associated with a bimaterial interface crack is proposed by including a wedge (made of a third material called interphase) with its vertex at the crack tip. The ensuing three-material wedge interface problem is analyzed using Williams' stress functions to extract the singularity. Different combinations of materials and wedge angles leading to real singularities are presented for some typical situations.
