A fracture criterion for piezoelectric ceramics is proposed which is based upon the energy release rate and two phase angles determined from the ratio between the intensity factors. It is assumed that the crack plane is at an angle to the poling direction within a symmetry plane of the body. The special cases of a crack perpendicular and parallel to the poling direction are presented. This criterion was implemented with experimental results from the literature in which the crack faces were perpendicular to the poling direction and the applied electric field. Excellent agreement was found between the fracture curve and the experimental results.
