Paper Abstract

Fatigue behavior for a piezoceramic material was studied. Fatigue tests using compact tension specimens of PZT-4 under various combinations of electric and mechanical load were conducted to develop a crack growth law. Experimental results indicated that crack growth could be significantly influenced by electric fields. The fatigue crack growth cannot be accounted for by stress intensity factor alone. The result of this study indicates that the mechanical strain energy release rate is a single parameter that can account for the combined mechanical and electrical load that governs crack growth. A Paris law type of fatigue crack model was derived based on the fatigue tests.
