A higher order displacement model for the plate analysis

Abstract

A higher order displacement model for laminated composite plates is presented. The displacement model has trigonometric terms in addition to thin plate terms and contains six unknowns. The model satisfies shear stress conditions at top and bottom of the plate. Governing equations and boundary conditions are obtained using virtual work principle. The present displacement model gives simple governing equations. The model has been applied to various simply supported rectangular isotropic, orthotropic and layered plates for static and free vibration analysis. This model yields better results as compared to other higher order displacement models.
