This research is about determining the effects of phase transitions in lead zirconate titanate. Transformations between tetragonal and rhombohedral phases have been implemented using an adapted evolution law. Predictions concering polycrystalline material behavior are made by the condensed method. Stresses and strains under electric loads are considered to investigate upcoming effects near the morphotropic phase boundary. An interpretation concerning actuator applications will be provided.
