Notes:
This paper presents results from quasi-static and high rate tensile testing of threealuminum sheet alloys, AA5754, AA5182 and AA6111, all of which are candidates for replacingmild steel in automotive bodies. Tests were performed at quasi-static rates using an Instronapparatus and at strain rates of 600 to 1500 s-1 using a tensile split Hopkinson bar. Additionally, anin-depth investigation was performed to determine the levels of damage within the materials and itssensitivity to strain rate.The constitutive response of all of the aluminum alloys tested showed only mild strain ratesensitivity. Dramatic increases in the elongation to failure were observed with increases in strainrate as well as greater reduction in area. Additionally, the level of damage was seen to increase withstrain rate
