Abstract The nonlinear buckling and the post-buckling response of the Fiber Metal Laminate (FML) column of channel section including delamination phenomenon is analysed. Numerical model of FML thin-walled profile is created in a commercial finite element software with the application of solid-shell elements and Cohesive Zone Method for a delamination area modelled by contact elements. The location of delamination plane is predicted by Hashin failure criteria. During the nonlinear buckling analysis, geometric imperfections are included and the non-linear behaviour of the aluminium is taken into account. Outcomes of numerical analysis were compared with experimental results.
