This paper investigates the fracture behavior of a piezoelectric material subjected to transient electro-mechanical loads. The piezoelectric medium contains a straight-line crack, which is parallel to its poling direction. The Fourier transform technique is used to reduce the problem to the solution of singular integral equations in Laplace transform plane. The Laplace inversion yields the results in the time domain. Some useful results are obtained. Strong coupling between stress and electric field near crack tips has been found.
