Abstract: The bending deformations of piezoelectric laminated plates subjected to combined applied voltage and loads were analyzed by using the proposed rectangular bending element. The correctness and efficiency of the element were verified by comparing the results with the data published in literatures. Also, the effects of the different ply angles of laminated plates (the unbalanced laminated plates) on the bending deformations of piezoelectric laminated plates were investigated. Finally, the deformations with partially debonding of piezoelectric actuators were studied. Based on the calculating results, it is found that the different area debonding between the actuator and the base plates may have significant effect on the composite plate bending deformations. The control ability of piezoelectric actuators might be lost in certain cases.

Key words: laminate, piezoelectric material, finite element, composite, debonding
