Local buckling, post-buckling and collapse of thin-walled channel section composite columns subjected to quasi-static compression

A post-buckling behaviour analysis and an ultimate load estimation of thin-walled composite channel columns under a constant rate of end shortening are presented. The columns with C-sections were made of a carbon-epoxy composite – a laminate consisting of eight symmetrically oriented plies. Four different layer arrangements were taken into consideration. The main objective of the study was to investigate the behaviour of the considered columns...
