Bending Analysis of Smart Functionally Graded CNT Reinforced Composite Plates

Abstract

Analysis of smart functionally graded plate of carbon nanotube reinforced composites combined with piezoelectric constituents has been introduced by finite element model (FEM). Material parameters of CNT reinforced composite plates are supposed to varies along the thickness direction following extended rule of mixture. Finite element model of the FG plates combined with piezoelectric materials is developed using ANSYS software. This model is tested against previously published work and found to be in accord with them. The numerical results are evaluated using verity boundary conditions. The effectiveness of piezoelectric materials for control of deflection of this FG plate is presented. The results revealed that the piezoelectric layer of the smart FG plates efficiently controls the nonlinear deformations of the presently studied smart CNT reinforced functionally graded plate. Results are also presented considering different material profiles for the grading of the FG plate.
