Aluminum alloys are being exploited for reducing the weight of automobiles in the ongoing efforts to improve energy efficiency. This study compares the performance of three joining methods, namely, spot welds, self-piercing rivets, and adhesive bonded, for aluminum AA5754-0 plate. Adhesive performance is also compared with three alloys; AA5754-0 which is a rolled sheet, extruded C210-T6, and cast A356-T6. Non-reinforced lap-shear joints were tested both quasi-statically and dynamically to compare the peak load before failure and total energy absorbed by the joint. In all cases, the aluminum samples had a protective coating applied at the mill.
