Abstract
In this paper, an analytical approach is presented to investigate the nonlinear static buckling and post-buckling for imperfect eccentrically stiffened functionally graded thin circular cylindrical shells surrounded on elastic foundation with ceramic–metal–ceramic layers (S-FGM) and subjected to axial compression. The Lekhnitsky smeared stiffeners technique with Pasternak type elastic foundation, stress function and Bubnov-Galerkin method are applied. Numerical results are given for evaluating effects of material and geometrical properties, elastic foundations and eccentrically outside stiffeners on the buckling and post-buckling of the S-FGM shells. The obtained results are validated by comparing with those in the literature.
