Effects of Electric Fatigue on Piezoelectric Ceramics
The fatigue behavior of piezoelectric ceramics PZT-5 subjected to three-point bending was investigated under a cyclic electric load coupled with a constant mechanical load. The direction of poling was perpendicular to that of the mechanical load. The fatigue life curves under high and low electric loading were compared. Non-linear relationship was observed between dS/dN and E/Ec.
