Accurate modelling of piezoelectric plates; single-layered plate

摘要

The paper presents an efficient two-dimensional approach to piezoelectric plates in the framework of linear theory of piezoelectricity. The approximation of the through-the- thickness variations accounts for the shear effects and a refinement of the electric potential. Using a variational formalism, electromechanically coupled plate equations are obtained for the Generalized stress resultants as well as for the generalized electric induction.
