Abstract

In this paper we describe the extension of our parameter identification algorithm for extracting the full parameter set of piezoelectric materials. The scheme is based on the FE solution of the according partial differential equations and on impedance measurements on appropriate test transducers. The results obtained by applying the scheme to a multilayer stack actuator as well as an ultrasound array antenna material will demonstrate the applicability of the developed parameter identification scheme
