The Effect of a Rigid Elliptical Inclusion on a Straight Crack

Abstract

The general problem of a straight crack near a rigid elliptical inclusion is solved. Complex potentials presented in a previous paper for the interaction of an edge dislocation with rigid ellipse are used to formulate the Green's function for this problem. The solution is written as a set of singular integral equations for crack opening displacement that are solved numerically. Stress intensity factors are presented for a variety of crack/inclusion geometries. Keywords: Cracks; Fracture mechanics; Singular integral equations; Greens functions; Stress analysis.
