| The study investigates the stability and failure of thin-walled composite structures with a top-hat cross section under axial compressive loading. The tested profiles were made of CFRP composite material by autoclaving. The scope of the research included experimental tests of real samples and numerical analysis by the finite element method using the ABAQUS® program. Both experimental tests and numerical analysis were performed over the full range of loading until structural failure. In experiments, postbuckling equilibrium paths and acoustic emission signals were measured, which allowed a comprehensive analysis of failure for the composite material. Numerical calculations were performed by progressive failure analysis, considering the failure initiation criteria under Hashin’s theory and failure evolution based on the energy criterion. Additionally, the cohesive zone model (CZM) was used to simulate delamination. Numerical results and experimental findings show high agreement. Moreover, the results reveal an interesting relationship between the compressive load and the buckling, postbuckling and failure of the analyzed structures. |
