Abstract

The electrical field saturation model is applied to the fracture prediction of piezoelectric materials containing electrically impermeable cracks. This model is analogously similar to the electric displacement saturation model that available in the literature. An electrical field saturation strip near the crack front is introduced in the analytical model. The stress intensity factor K and the energy release rate G are obtained in closed-form. It is found that fracture predictions based on K and G criteria are identical. Fracture predictions based on the electric field saturation model and the electric displacement model are also found to be the same.
