Static analysis of functionally graded plate in thermal environment using HDQ-DQ method

A three-dimensional elasticity theory is presented for the investigation of displacements and stresses in FG square plate subjected to thermal loadings. The material properties are assumed to be graded in the thickness direction, which vary according to the simple power law distribution. Differential quadrature(DQ) and harmonic differential quadrature(HDQM) methods are adopted to solve the equilibrium equations. The accuracy of the method is demonstrated by comparing the results with those of the existing solutions.
