Abstract

This paper assesses computationally the thin-walled column structure with multi cell and aluminum alloy 6061-O against dynamic compression in the axial direction. The dynamic explicit was employed in the Abaqus code to study characteristics of the cross section differences. The complex proportional assessment (COPRAS) method was employed to determine a configuration that complies with the indicator parameters. The chosen cross-section configuration is further enhanced by creating elliptical holes with different diameter ratios. The results show that the thin-walled column structure with a nine-cell cross-section accompanied by an elliptical hole ratio of 0.3 indicates the potential corresponding to the indicator parameters for the crashworthiness application.
