Use of Classical Plate Finite Elements for the Analysis of Electroactive Composite Plates: Theoretical Aspects

ABSTRACT: Smart structures including piezoelectric materials have been under interest for many years. As a consequence many piezoelectric finite elements have been developed to simulate the behavior of such structures. The present article is focused on the development of an original plate theory based upon a priori assumptions for active vibration control applications. The main result of this theory lies in the removal of electrical variables from the problem unknowns, according to the electric boundary conditions. The electromechanical effects are then taken into account via elastic coefficient modifications and external electric loads. Key Words: piezoelectricity, plate theory, a priori assumptions, no electric degree of freedom
