AN ARBITRARILY-ORIENTED PLANE CRACK TERMINATING AT THE INTERFACE BETWEEN DISSIMILAR PIEZOELECTRIC MATERIALS

The plane problem of a crack terminating al the interface of a bimater ial piezoelectric, and loaded on its faces, is treated. Emphasis is pl aced on how tb transform this problem into a nonhomogeneous Hilbert pr oblem. To make the derivation tractable, the concept of the axial conj ugate is introduced and related to the complex conjugate. The angle be tween the crack line and the interface may be arbitrary.
