Static analysis of piezoelectric functionally graded porous plates reinforced by graphene platelets

Vibration and Static Analysis of Functionally Graded Porous Plates

This research deals with free vibration and static bending of a simply supported functionally graded (FG) plate with the porosity effect. Material properties of the plate which are related to its change are position-dependent. Governing equations of the FG plate are obtained by using the Hamilton’s principle within first-order shear deformation plate theory. In solving the problem, the Navier s...

Nonlinear Vibration Analysis of Piezoelectric Functionally Graded Porous Timoshenko Beams

In this paper, nonlinear vibration analysis of functionally graded piezoelectric (FGP) beam with porosities material is investigated based on the Timoshenko beam theory. Material properties of FG porous beam are described according to the rule of mixture which modified to approximate material properties with porosity phases. The Ritz method is used to obtain the governing equation which is then...

Three dimensional static analysis of two dimensional functionally graded plates

In this paper, static analysis of two dimensional functionally graded plates based on three dimensional theory of elasticity is investigated. Graded finite element method has been used to solve the problem. The effects of power law exponents on static behavior of a fully clamped 2D-FGM plate have been investigated. The model has been compared with result of a 1D-FGM plate for different boundary...

Vertically Reinforced 1-3 Piezoelectric Composites for Active Damping of Functionally Graded Plates

M ONOLITHIC piezoelectric materials (PZTs) have been widely used as distributed sensors and actuators for developing smart structures with self-monitoring and selfcontrolling capabilities [1–10]. However, their major drawback is low control authority as the magnitude of their electromechanical coefficients is very small. The situation can be improved by using an active constrained layer damping...
