Nonlinear finite element modeling of vibration control of composite piezolaminated composite plates and shells

摘要

This paper addresses the theory and finite element analysis of the transient large amplitude vibration response of thin composite structures and its control by integrated piezoelectric layers. A geometrically nonlinear finite shell element for the coupled analysis of piezolaminated structures is developed that is based on the first-order shear deformation (Reissner-Mindlin) hypothesis and the assumptions of small strains and moderate rotations of the normal. The finite element model can be applied to smart structures consisting of a composite laminated master structure with arbitrary ply lay-up and integrated piezoelectric sensor and actuator layers or patches attached to the upper and lower surfaces.
