In this study, the buckling analysis of layered cylindrical shells with functionally graded material face sheets subjected to an axial compressive load is investigated. The dimensionless axial buckling load of layered cylindrical shells with functionally graded material face sheets is obtained. Effects of volume fractions of functionally graded material face sheets and cylindrical shell characteristics on the dimensionless axial buckling load have been studied.

In this study, the non-linear stability of three-layered conical shells with functionally graded core have not been investigated previously. The purpose of this paper is to study this problem. The large deflection theory with von Karman-Donnell-type of kinematic non-linearity is used to deduce the basic equations. The basic equations are solved analytically by using superposition and Galerkin methods. The influences of several parameters on the dimensionless non-linear critical axial loads are discussed.

In this study, the stability analysis of three-layered shells containing a functionally graded material layer in the surrounding medium and subjected to the uniform lateral pressure is investigated. The surrounding elastic medium is modeled as a Pasternak foundation. The dimensionless critical lateral pressures of three-layered functionally graded material shells with and without elastic foundations are obtained. Effects of compositional profiles and elastic foundation on the dimensionless critical lateral pressures have been studied.
