Abstract:

© 2015 - IOS Press and the authors. All rights reserved. The present paper derives a 3-D finite element formulation and an iterative algorithm for multiphysics analysis of coupled anomalous photovoltaic, photo-thermal and pyroelectric effects in PbLaZrTi (PLZT) ceramics. The distinction in the computation aspects of electrical potential, electrical field strength and electrical charge for 0-1 and 0-3 polarized PLZT wafers are discussed thoroughly. The element performance is improved by using an assumed natural strain approach and an enhanced assumed strain method. The transverse displacements of a bimorph 0-1 polarized PLZT actuator were predicted using the present finite element formulation and then verified with the existing analytical solution and experimental results. The static analysis of a cantilevered beam bonded with a 0-1 or 0-3 polarized PLZT actuators was also presented and compared with the theoretical solutions. The numerical simulations demonstrate that the present formulations and algorithm possess superior performance.
