Modern smart piezoelectrics such as low-voltage multilayer piezoelectric actuators consist of stacks of piezo-ceramic layers with interdigitated metallic electrodes in between. During their technical application mechanical stresses are an inherent loading scenario of such electro-mechanical converter components. Therefore, a detailed knowledge of the coupled phenomena among the field-type quantities such as mechanical stress, electrical field strength and temperature is absolutely necessary to guarantee demanded structural and functional integrity. A theoretical simulation is the only way to obtain these physical relevant field-quantities within piezo-electric devices. Hence, for FE-analysis of the highly nonlinear material behavior of piezoelectrics, basic modeling parameters have to be determined. Usually, such constitutive laws implemented into FEA-tools are parameterized by experiments as realized in this work.
