The development of a generalized layer-wise laminate model using high-order approximations for the field variable through-the-thickness of a composite laminate is presented. The model is used to perform both static and dynamic analysis of an unsymmetrical, three-layer laminated beam where the only deformation input is the actuation strain induced in the piezoelectric layer. The resulting induced displacements and inter-laminar stresses in the beam are calculated. The modal amplitudes and vibration of the beam that is harmonically activated by a piezoelectric layer are investigated. The beam behaviour predicted by increasing the order of approximation through-the-thickness variables are compared to ascertain the level of model complexity necessary to accurately represent piezoelectric actuation of laminated beam.
