In this study the plane strain crack problem for a layered piezoelectric plate with a finite crack is considered. The laminated slab is made of a piezoelectric slab bonded between two elastic layers of different physical properties. The Fourier transform techniques are used to reduce the problem to that of solving a singular integral equation. The singular integral equation is solved by using the Gauss-Jacobi integration formula. Numerical calculations are carried out, and the main results presented are the variation of the energy density factors as functions of the geometic parameters, the material properties and the electrical boundary conditions of the layered composites.
