Measured Constitutive Behavior of Several Compositions of PZT


 PZT is often used as an actuator material. The actuation properties are dependent on several factors including composition, grain size, and processing; as well as on loading and load history. The effect of grain size and composition on the hysteresis behavior of PZT was experimentally characterized. The results show the effects of preload stress and temperature on the actuation capability of this class of materials.
