In this paper the interaction of a screw dislocation with a semi-infinite interfacial crack of two dissimilar piezoelectric materials is considered. The expressions for the electroelastic fields, intensity factors, and image force acting on a screw dislocation are given in explicit form in terms of
The present work investigates the problem of multiple cracks on the arc-shaped interface of a semi-cylindrical magneto-electro-elastic layer bonded onto an orthotropic substrate. Continuously distributed dislocation is used to simulate the anti-plane interfacial cracks. The problem is formulated as
