Effect of through-holes on quasi-static axial compression behaviors of aluminum with thin-walled structure

Abstract

Abstract The effect of through-holes position on deformation behaviors and energy absorption of 6063 aluminum alloy with thin-walled structure, taking the same number and different positions of through-holes, will be investigated by quasi-static axial compression using universal testing machine. The experimental results show that the compression behavior of thin-walled structure specimens can be significantly improved by properly opening through-holes and selecting appropriate locations. Based on the experimental data, the fluctuation degree of sample load was reduced. The stability of compression deformation was improved. The first peak load was reduced. And the energy absorption performance of the specimens was improved.
