A novel Inverse Method for the determination of material parameters characterizing discoidal piezoceramic actuators is presented. In contrast to the common identification method, no specially shaped test samples are required. The Inverse Method is based on a finite element simulation. Both the measured mechanical and the electrical behavior of the actuator serve as input quantities of the new procedure. The presented results show the efficiency and correctness of the developed Inverse Method.
