Abstract
In piezoceramic actuators normally a linear behavior is observed if the excitation is done by a weak electric field. In this paper, however, it is shown that if the system is excited near resonance even for a weak electric field strong nonlinearities may occur. As an example a piezoceramic transformer is investigated. The transformer is simulated using linear constitutive equations. For a very low excitation voltage the simulated results agree well with experimental results. For a moderate excitation voltage the experiments show that linear theory cannot describe all results and nonlinear constitutive equations have to be used.
