Paper Abstract

A finite element formulation based on higher-order shear deformation theory is presented for modeling the behavior of laminated composite plates with piezoelectric elements under static and dynamic loadings. This model is valid for both continuous and segmented piezoelectric elements that are either surface-bonded or embedded in the laminated plate. Voltage is not introduced as an additional degree of freedom in the present model and the piezoelectric elements on the upper and lower surfaces of the plate are used as actuators. The effect of actuator voltage on the static and dynamic behavior of such plates having different edge conditions and width-to-thickness ratio has been studied.
