Experimental-numerical analysis reveals the influence of cross-section shape on stability in carbon-epoxy composites, indicating potential design improvements.
The paper aims experimental-numerical approaches to the behaviour of the compressed thin-walled composite profiles with closed sections. For this, thin-walled composite profiles made of carbon-epoxy composite from the autoclave technique. It was to analyse the effect of cross-section shape on the stability and fracture of composite structures. This was covered through a universal testing machine, an optical deformation measurement system, acoustic emission method as well as a microscope. Numerical simulations were carried out using the finite element method (based on progressive failure analysis). The research follows the project from the National Science Centre in Poland, Reg. No. 2021/41/B/ST8/00148.
