Abstract
In this study, the nonlinear buckling of stiffened FGM truncated conical shells resting on an elastic foundation and subjected to a uniform axial compressive load is considered. The shells are reinforced by FGM stringers and rings. Using the analytical approach, FSDT, Galerkin method, geometrical nonlinearity in the von Karman–Donnell sense, and Leknitskii smeared stiffener technique, the governing equations are derived. Closed-form expressions for determining the critical buckling load and for analyzing the postbuckling load–deflection curves are obtained. Finally, the effect of stiffeners, dimensional parameters, semivertex angle, material properties, and foundations on the nonlinear response of FGM truncated conical shells are analyzed and discussed in detail.
