The problem of shape control of curved shell structures with the least piezoelectric actuators in the most reasonable layout at optimal multi-point voltages was addressed. First, a solid shell element for shell structures was constructed with the HS-ANS method, to overcome shear locking, trapezoidal locking and thickness locking. Second, the layout of actuators was designed through the GA combinatorial optimization and the input actuator voltage was decided with the GA numerical optimization. The general computation processes were also built respectively. The following examples show the effectiveness of the proposed solid shell element and optimization method to control deformation of the curved shell structures. [ABSTRACT FROM AUTHOR]
