| In the paper a numerical analysis of both critical and post-critical state of a thin-walled channel section simply supported beam under axial compression. The beam was made of carbon-epoxy symmetrical composite prepared with a pre-preg technology using 8 layers of unidirectional band. The numerical simulations were performed with Finite Elements Method (FEM) in Abaqus and Ansys environment and an analytical-numerical method based on the Koiter theory of conservative systems stability. The value of critical load was estimated according to the Tsai-Wu stress criterion. The performed calculations enabled critical state identification, as well as deformation states and effort analysis of the laminate structure in post-critical state. |
