| This paper relates to experimental and numerical analyses of damage of a thin-walled laminated angle column. Limit and post-buckling states of the simply-supported column under uniform compression were investigated. Geometric imperfections of real samples were identified by 3D scanning. Flexible pads were used to prevent stress concentration where the column contacts with the rigid support plates. First, experiments were conducted on a testing machine using the Aramis system for column strain measurement. After that, a numerical model reflecting the real system was designed in Abaqus. A progressive damage analysis of the thin-walled angle columns was performed by the finite element method. Experimental and numerical post-buckling equilibrium paths were compared. Numerical and experimental results showed high agreement, both in qualitative and quantitative terms. The same failure mechanism was obtained in the experiments and in the numerical analysis, i.e. flange damage (crack) in the column centre. |
