In this contribution, we exploit an Inverse scheme enabling the identification of temperature dependent material parameters of piezoceramic materials as well as their electromechanical coupling factors. This information is indispensable to predict the behavior of sensors and actuators incorporating such materials. Principally, the identification procedure is based on an iterative adjustment of finite...
We present a mathematical Inverse Method providing reliable material parameters of piezoceramic materials. Thereby, a systematic matching of finite element simulations to measurements yields the complete set of material parameters. Contrary to our previous research where we utilized both, frequency resolved electrical impedances and spatially resolved surface velocities, only the impedance curves...
By means of numerical simulations, the efforts for the development of piezoceramic transducers can be considerably reduced. However, reliable simulations of the transducer's behavior require precise material parameters which can not be obtained with common parameter identification methods. Therefore, we use an alternative approach to determine these parameters, the so-called Inverse Method. Basically,...
The reliability of Finite Element based simulations of the electrical and mechanical behavior for piezoceramic actuators strongly depends on the accuracy of the required material parameters. For many transducer shapes, the standard methods in order to determine the material parameters are not applicable. Therefore, we developed an alternative method for the parameter estimation, namely the Inverse...
