Opis:: Buckling and postbuckling behaviour of thin-walled channel section beam made of epoxy-glass composite have been consid-ered. The beams under analysis was subjected to pure bending. The main aim was check the influence of ply arrangement on buckling load and postbuckling behaviour and validate the authors analytical-numerical method by commercial finite element method software. Mentioned analytical-numerical method has been developed for more than 25 years in Department of Strength of Materials. This method uses asymptotic Koiter theory for conservative systems in the second order approximation modified by Byskov and Hutchinson. Additional-ly, using the finite element method software the influence of ply arrangement on failure load were checked.

Opis:: A review of papers that investigate the static and dynamic coupled buckling and post-buckling behaviour of thin-walled structures is carried out. The problem of static coupled buckling is sufficiently well-recognized. The analysis of dynamic interactive buckling is limited in practice to columns, single plates and shells. The applications of finite element method (FEM) or/and analytical-numerical method (ANM) to solve interaction buckling problems are on-going. In Poland, the team of scientists from the Department of Strength of Materials, Lodz University of Technology and co-workers developed the analytical-numerical method. This method allows to determine static buckling stresses, natural frequencies, coefficients of the equation describing the post-buckling equilibrium path and dynamic response of the plate structure subjected to compression load and/or bending moment. Using the dynamic buckling criteria, it is possible to determine the dynamic critical load. They presented a lot of interesting results for problems of the static and dynamic coupled buckling of thin-walled plate structures with complex shapes of cross-sections, including an interaction of component plates. The most important advantage of presented analytical-numerical method is that it enables to describe all buckling modes and the post-buckling behaviours of thin-walled columns made of different materials. Thin isotropic, orthotropic or laminate structures were considered.
