Bending-Stretching Analysis of Thick Functionally Graded Rectangular Plate Based on Higher Order Shear and Normal Deformable Theory

In this article, bending-stretching analysis of thick rectangular plate made of functionally graded material has been investigated based on higher order shear and normal deformable theory which was introduced by Batra and Vilodi. In this theory, both shear and normal deformation effects in the thickness direction are considered. Also, the deflection of plate is not considered as a constant in the thickness direction. A power law function is used to describe the mechanical properties of the functionally graded plate. The numerical results have been presented for first to fifth order shear and normal deformable theory in tables and diagrams. The effects of functionally graded material properties on deflection and stresses of plate have been studied for various thickness and dimensions of the plate. It is shown that this theory gives accurate results not only for thin and moderately thick plates, but also for functionally graded thick plates.
