Abstract 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.

Abstract A three-dimensional, meso-electro-mechanical model has been formulated for description of PMN-PT-BT ceramics. Unlike the experimentally fit models and phenomenological models which are based on state variables and/or empirical relationships, this fully coupled, computational mesomechanics model for polycrystalline PMN-PT-BT ceramics is developed based on considerations of constitutive behavior of single crystals. Specifically, domain wall nucleation and evolution rate equations are proposed in this work to describe the nonlinear hysteresis behavior of these ceramics near the phase transition temperature with maximum permittivity.
