Pseudo-Three-Dimensional Analysis for Functionally Graded Plate Integrated with a Piezoelectric Fiber Reinforced Composite Layer

Abstract EN

In this paper, a pseudo-three-dimensional method is proposed to investigate static behavior analysis of functionally graded (FG) plate integrated with a piezoelectric fiber reinforced composite (PFRC) layer by the hyperbolic shear and normal deformation theory.

The present method is a displacement-based theory which accounts for hyperbolic variation of in-plane displacement field and parabolic variation of transverse displacement field.

The linear electrical potential function in the PFRC layer is modeled.

The governing equations of present method are derived by the minimum potential energy principle and Navier’s procedure is used to solve the equations.

Numerical results are presented to demonstrate the efficiency of the proposed method.

The effects of some parameters including material composition, aspect ratios, and applied voltages on the deformations of the plate are investigated.

Compared with the available data of numerical method and 3D method, the presented method is more suitable for the smart FG structure.
