Abstract
AbstractIn this contribution, a free–locking shell element with piezoelectric ceramic layers is presented. The material law and the constitutive equations of the coupled electro–mechanical problem are derived in convective coordinates, so that the presented element accounts for geometrical nonlinearities [2]. To avoid zero–energy mode and locking effects of the thin shell structure, assumed natural strain (ANS) method [1] is implemented. Finally, some numerical examples demonstrate the ability of this element to solve linear and nonlinear problems. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
