Theoretical formulation based on the first-order shear deformation shell theory (FSDST) is presented for the analysis of functionally graded (FG) cylindrical shells subjected to axisymmetric thermomechanical loadings. Also a cylinder made up of a FG layer at the mid-depth and two equal-thickness ceramic and metal layers at the inner and outer surfaces of the cylinder, respectively, is analyzed. The axisymmetric heat transfer equation and the governing equilibrium equations are solved analytically. To check the correctness and accuracy of the present method, the results achieved from this theory are compared with those obtained by utilizing a commercial finite element package. The results show that there are close agreements between the present solutions and those obtained from the finite element method. Finally, the effect of the imposed thermomechanical loading on the response of the FG cylindrical shell is discussed.
