摘要: A moving polarization saturation (PS) model is proposed to study the plane problem of a Yoffe-type crack with constant velocity in ferroelectric materials considering electric saturation. Based on extended Stroh formalism, solved using complex function method. The closed-form expressions for electroelastic fields are obtained concise way. Results shown converge known solutions static PS and linear piezoelectric model. Numerical results PZT-5H material given graphically. It can be deducted that dynamic intensity factors dependent field velocity. predicts propagation may promoted by positive applied electrical inhibited negative one. For high velocity, 0.28 times minimum body wave speed, hoop stress maximal an angle qs0.
