“…The high agreement of result is conditioned by proper preparation of the numerical models (verified by experimental tests). Additionally, by comparing the obtained results for the top-hat column with the results presented in a previously published paper [ 45 ], it is possible to evaluate the influence of the stacking sequence on the load-carrying capacity of the composite structure. In the case of the structure presented in the previous publication [ 45 ], characterized by the lay-up [0/–45/45/90] s , two half-waves were observed in terms of the structure stability, and the failure load was equal to P f = 17,084 N (FEM).…”

“…Material properties (both mechanical and strength properties) were determined using a universal testing machine (UTM)—Zwick Z100 (ZwickRoell GmbH & Co. KG, Ulm, Germany). All mentioned properties were determined using ISO standards (ISO 14126—static compression test, ISO 527—static tensile test, ISO 14129—shear test) [ 45 ]. The mechanical and strength properties of the composite material are presented in Table 1 [ 56 ].…”

“…The subject literature has already described studies of the phenomenon of failure (including the phenomenon of delamination) of thin-walled composite materials. Those studies are mainly based on the example of columns with top-hat cross-section [ 45 ], which have higher load capacity and different geometrical parameters than those in the current research. This paper presents the phenomenon of failure in more details by comparing the failure results of top-hat and channel structures (which is the main difference in relation to previous research works).…”

The paper analyzes the stability and failure phenomenon of compressed thin-walled composite columns. Thin-walled columns (top-hat and channel section columns) were made of carbon fiber reinforced polymer (CFRP) composite material (using the autoclave technique). An experimental study on actual structures and numerical calculations on computational models using the finite element method was performed. During the experimental study, post-critical equilibrium paths were registered with acoustic emission signals, in order to register the damage phenomenon. Simultaneously to the experimental tests, numerical simulations were performed using progressive failure analysis (PFA) and cohesive zone model (CZM). A measurable effect of the conducted experimental-numerical research was the analysis of the failure phenomenon, both for the top-hat and channel section columns (including delamination phenomenon). The main objective of this study was to be able to evaluate the delamination phenomenon, with further analysis of this phenomenon. The results of the numerical tests showed a compatibility with experimental tests.

The current study investigates the stability and failure analysis of thin-walled composite columns with a top-hat and channel cross section, subjected to axial compression. The analyzed structures were made of composite material (carbon fiber reinforced polymer) by autoclave technique. The study included experimental tests on actual specimens and numerical simulations on numerical models using finite element method (in ABAQUS® program).Experimental-numerical analysis was conducted over the full range of loading (until failure phenomenon). Regarding the experimental tests, postbuckling equilibrium paths as well as acoustic emission signals were registered, which directly allowed for comprehensive analysis of failure phenomenon of composite material. In case of numerical simulations, two independent numerical damage models were used. The first one constitutes the progressive failure analysis, considering the damage initiation criteria using Hashin's theory and damage evolution based on the energy criterion. The second one constitutes the cohesive zone model, which was used to simulate failure of composite material caused by delamination phenomenon. Both experimental and numerical results show high agreement. Furthermore, the obtained results reveal an interesting relationship between buckling, postbuckling, and failure phenomenon of the analyzed structures.
