A finite element technique is used to study the angular distributions of the energy release rates and stresses for the crack propagation in a piezoelectric ceramic because of the applied stress and applied electric field. The change in total energy is compared with the theoretical values of the ener

There is confusion in the literature about the boundary condition when crack problems in piezoelectric materials are explored. For example, recently Suo et al. [1] studied cracks both in piezoelectrics and on interfaces between piezoelectrics and other materials. They used the boundary condition in
