| The study investigates short thin-walled channel section columns made of a carbon-epoxy laminate. The tested columns were subjected to compression, including an eccentric compressive load relative to the gravity center of the cross section of the column. The boundary conditions applied in the study reflected simple support of the column. The scope of the study involved determining the effect of eccentric load on the structure’s stability and load-carrying capacity. At the same time, a numerical analysis by the finite element method was performed using the commercial simulation software Abaqus®. The non-linear numerical analysis of the compressed profiles was performed by the Newton-Raphson method. Failure of the composite material was described using a progressive damage model, wherein damage initiation in the composite material was described based on Hashin’s failure criteria while the evolution of damage was described by the energy-based progressive damage criterion. Results predicted by the numerical model were validated by experimental tests performed on real structures. The results enabled a comprehensive description of the composite material’s failure, starting from failure initiation until the total loss of load-carrying capacity of the column. |
