Abstract: Kirchoff hypothesis is applied to laminate plate with induced strain actuators. Piezoelectric patch is bonded to its surface or embedded within the laminate. Using plate element, FEM(Finite Element Method) for laminate plate with induced strain actuators is proposed. Considering the control matrix, which is gotten from applied voltage to laminate plate, the needed applied voltage is given for any plate shapes using optimization algorithms. Numerical example is presented. Comparison between experiments and FEM is shown up in this paper. Three solutions of unconstrained optimization, constrained optimization and optimization considering energy consumption,are given.
