This paper is concerned with an analytical formulation and a numerical solution of thermal stress and deformation for moderately thick shells of revolution made of functionally graded material (FGM) subjected to thermal loading due to fluid. The temperature distribution through the thickness is experessed using a curve of high order, and the temperature field in the shell is determined using the equations of heat conduction and heat transfer. the equations of equilibrium and the relations between strains and displacements are derived from the Reissner-Naghdi shell theory. The fundamental equations derived are numerically solved using the finite difference method. As numerical examples, functionally graded cylindrical shells composed of SUS 304 and ZrO_2 subjected to thermal ioads due to fluid are analyzed. The results show that the present method gives correct temparature distributions and that the temperature distributions, stress distributions and deformations vary significantly depending on the compositional distribution profiles in FGM.
