This paper is concerned with the numerical analysis of dynamic thermal stress and deformation for moderately thick shells of revolution made of functionally graded material by using finite element method. The material properties of the shell are continuously inhomogeneous along the shell thickness and dependent on the temperature. The temperature distribution through the shell thickness is expressed with a curve of high order, and thick shell elements are utilized for the analysis. As a numerical example, a functionally graded material shell composed of SUS304 and PSZ subjected to thermal loads due to heat generation in the shell body is treated. The shell is axisymmetric and has a parabolic meridian. It is found that temperature distributions, stress distributions and deformations are significantly influenced by temperature dependent properties of the materials.
