Crack problem at interface of piezoelectric strip bonded to elastic layer under anti-plane shear

Using the theory of linear piezoelectricity, the problem of two layered str ip with a piezoelectric ceramic bonded to an elastic material containing a finite interface crack is considered. The our-of-plane mechanical and inpla ne electrical loadings are simultaneously applied to the strip. Fourier tra nsforms are used to reduce the problem to a pair of dual integral equations . which is then expressed in terms of a Fredholm integral equation of the s econd kind. The stress intensity factor is determined, and numerical analys es for several materials are performed and discussed.
