Shape Control in Composite Laminates Using Piezoelectric Actuators considering Thermal Deformation

Based on the first order shear deformation plate theory, a numerical analysis model of composite laminated plates with distributed PZT actuators under thermal load was established, and the corresponding formulae of finite element method were presented considering the effect of adhesive layer between PZT actuator and plate. For a two ends simply supported plate, the thermal deformation of the plates induced by different temperatures on the upper and lower surfaces and the thermal deformation compensation for the plates using PZT actuators were studied, then the optimization of voltages applied to each actuator was discussed.
