Temperature stresses in Functionally graded (FGM) material plates using deformation theory-Analytical approach

The advancement in the field of composites lead to the development of a new material called Functionally graded materials (FGMs). The concept of grading two distinct materials is introduced in FGMs to withstand high temperature variations across thin section. In this study analytical formulations and theoretical solutions were developed for the FGM plates subjected to thermal loads using refined computational model based on First Order Shear Deformation Theory (FSDT). Material properties are based on Powerlaw function. The effects of thermal stresses are studied for constant, linear and nonlinear variation of temperatures across the thickness of the plate, whereas in-plane is assumed to be sinusoidal. The accuracy of solutions are established with the literature. Parametric studies are performed and numerical results are presented for the simply supported FGM plates. Comparative studies are performed between various temperature profiles and bench mark results are presented for displacements, in-plane and transverse stresses. (c) 2021 Elsevier Ltd.
