Abstract

The influence of piezoceramic actuator nonlinearities on the response of a panel-enclosure system is examined. As an extension of our earlier work, hysteresis effect is also included in the nonlinear relationship between the free strain experienced by a piezoceramic patch and the applied electric field. The responses of the system with the hysteretic effect are discussed and compared with experimental results.
