The elasto-plastic buckling and postbuckling of fiber metal laminates(FML) are studied in this research. Considering the geometric nonlinearity of the structure and the elastoplastic deformation of the metal layers, the incremental Von Karman geometric relation of the FML with initial deflection is established. Moreover, an incremental elasto-plastic constitutive relation adopting the mixed hardening rule is introduced to depict the stress-strain relationship of the metal layers. Subsequently, the incremental nonlinear governing equations of the FML subjected to in-plane compressive loads are derived, and the whole problem is solved by the iterative method according to the finite difference method. In numerical examples, the effects of the initial deflection,the loading state, and the geometric parameters on the elasto-plastic buckling and postbuckling of FML are investigated, respectively.
