摘要
The influence of the imperfection sign (sense) on local postbuckling equilibrium path of plates made of functionally graded materials (FGMs) has been analyzed. Koiter's theory has been used to explain this phenomenon. In the case of local buckling, a nonsymmetrical stable equilibrium path has been obtained. The investigations focus on a comparison of the semi-analytical method (SAM) and the finite element method (FEM) applied to the postbuckling nonlinear analysis of thin-walled complex FG plated structures.
