Experimental Studies Thin-Walled Circular Aluminium Tubes under Axial Loading

摘要

This paper presents the results of experiments conducted on the axial collapse behaviour of circular thin-walled (D/t-10 approx 450) aluminium alloy tubes with lengths L/D <= 10. The aluminium tubes tested were commercial 6060 alloy in the as-received, hardened T5 condition. Tests were conducted under quasi-static conditions (d#epsilon#/dt approx= 10~(-4)). A collapse mode classification chart is presented and observations made.
