Abstract
Smart structures with active ceramic segments typically consist of piezoceramic layers bonded to elastic members. Analytical modeling of piezoceramics has been addressed by many authors. Developments to date allow one to model planar structures and homogeneous piezoceramic continua. Most smart structures with piezoceramic control layers have multi- layered plate and shell geometries distributed in three-dimensional space. In this study, a composite shell finite element is developed for modeling such structures. The element developed is a general quadrilateral shell with eight nodes and curved edges. This paper describes the development of the element including a method for modeling the excitations to the bonded piezoceramic. Analytical and experimental results are presented for a commercial bimorph validating the performance of the element.
