Abstract :
Static compression and repeated compression fatigue tests were carried out for piezoelectric ceramics of the PZT family with dimensions of 5 mm in diameter and 10 mm in length. Both tests were conducted under three electrically different conditions to investigate the effects of poling in the samples. It was clarified as a result that the poled samples have a higher compressive strength and fatigue resistance when used between electrically insulated jibs. The correlation between changes of piezoelectric properties and the number of fatigue cycles is discussed
