Abstract

For the sake of improving the static mechanical properties and decreasing the exterior protrusion height of the clinched joint, a mechanical rivet-reinforcing process with different reinforcing loads was carried out to join AA5052 sheets in this study. Tubular rivets with 1 mm wall thickness were used to conduct the rivet-reinforcing experiment. The static strength, failure mode, neck thickness, interlock value and energy absorption of the rivet-reinforced joints realized with different reinforcing loads were comprehensively analyzed by experimental method. With the gradual increase of the reinforcing load, the interlock value and neck thickness were enlarged, while the height of exterior protrusion was decreased. When the reinforcing load was 45 kN, the height of exterior protrusion was decreased from 1.17 to 0.52 mm. The energy absorption and average static strength of dissimilar rivet-reinforced joints were significantly higher than that of the conventional clinched joints. The average strength was increased from 1835.23 to 4032.87 N in the single-lap-shear test, and from 1395.02 to 1658.99 N in the cross-lap-tensile test. The energy absorption of joint was increased from 1.34 to 6.77 J in the single-lap-shear test, and from 4.26 to 9.18 J in the cross-lap-tensile test. It was proved that rivet-reinforcing process with tubular rivet can effectively increase the mechanical properties of the conventional clinched joints.
