| Abstract: | In this paper, the analytical procedure for functionally gradient material(FGM)plates is developed based on the classical theory of laminated plates andthe computational mathematical method.Temperature solutions are obtained forthe steady state. Utilizing the material properties of each hypothetical layer,theeffective properties are estimated and thermal stress distributions are caloulated. |
