In this paper, a new three-dimensional thin-shell structure containing an integrated distributed piezoelectric sensor and actuator is proposed. The distributed piezoelectric sensor layer monitors the structural shape deformation due to the direct effect and the distributed actuator layer suppresses the deflection via the converse piezoelectric effect. A finite-element formulation is presented for modelling the dynamic as well as static response of the laminated shell with piezoelectric sensors/actuators. An eight-node and 40 degrees of freedom shell element is built. The performance of the shell elements is improved by a reduced integration technique. The shell element is verified by calculating a piezoelectric polymeric PVDF bimorph beam. The results agreed fairly well with those obtained through theoretical analysis by Tzou and Tseng and Hwang and Park.
