Failure Loads of Spot Friction Welds in Aluminum 6111-T4 Sheets under Quasi-Static and Dynamic Loading Conditions 2007-01-0983
In this investigation, spot friction welds in aluminum 6111-T4 lap-shear specimens were tested under both quasi-static and dynamic loading conditions. Micrographs of the spot friction welds after testing were examined to understand the failure modes of spot friction welds in lap-shear specimens under different loading conditions. The micrographs indicate that the spot friction welds produced by this particular set of welding parameters failed in interfacial failure mode under both quasi-static and dynamic loading conditions. The load and displacement histories for lap-shear specimens were obtained under quasi-static and dynamic loading conditions at three different impact velocities. The failure loads of spot friction welds in lap-shear specimens under dynamic loading conditions are about 7% larger than those under quasi-static loading conditions. The effects of the impact velocity and the separation velocity on the failure load of the spot friction welds in lap-shear specimens are also discussed.
