Abstract

Stress analysis is carried out in an orthotropic strip containing a Volterra-type screw dislocation. The distributed dislocation technique is employed to obtain integral equations for a strip weakened by cracks and cavities under antiplane traction. These equations are of Cauchy singular kind, which are solved numerically by generalizing a numerical method available in the literature. Several examples are solved to demonstrate the validity and applicability of the procedure.
