Abstract:1420 aluminum鄄lithium alloy sheets (AL1420) with itself, H62 copper alloy sheets (H62), Q215 gal鄄
vanized steel sheets (Q215) and TA1 industrial pure titanium sheets (TA1) were applied to fabricated different types of
single鄄lap self鄄piercing riveted joints. The static failure loads and energy absorption properties of the joints were ana鄄
lyzed using the static tests, and the macroscopic failure mechanisms were discussed and inferred based on the failure
modes of the joints. The results show that: TA1鄄AL1420 joints have the highest static failure loads, and Q215鄄AL1420
joints possess the optimum energy absorption properties; except for TA1鄄AL1420 joints, the laws of the failure displace鄄
ments are consistent to those of the energy absorption values for the other type joints. When the gap of the yield
strengths between the upper and lower sheets was small, the failure modes of the joints were the lower sheets separated
with the rivet; when it was large, the joints mainly failed due to the sheets with lower yield strength fractured.
