摘要：

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. (C) 2013 Elsevier Ltd. All rights reserved.
