Abstract
This paper presents the theoretical basic to study FGM cylindrical shells by using the quasi-3D higher-order shear deformation theory. The displacement field accounts for a cubic variation of the inplane displacements and a quadratic variation of the transverse displacement through the thickness. The material volume distribution of the shell is given in a form of a power function of thickness. The mathematical model and the computational program are validated through a comparison with previous results. Based on the mathematical model and the computational program, the paper presents the effect of several parameters, including the thickness and the coefficient of material distribution on the stress-strain state of a shell subjected to external load.
