On the Plane Piezoelectric Problem of a Loaded Crack Terminating at a Material Interface

The plane problem of a crack terminating at the interface of a bimaterial piezoelectl:ic, and loaded on its fa.ces, is treated. The emphasis is placed on how to transform this problem into a non-homogeneous Hilbert problem. To make the derivation tractable, the concept of the axial conjugate is introduced and related to the complex conjugate. The angle between the crack line and the interface may be arbitrary. Numerical results are given to illustrate the stress singularity at crack tip.
