Fracture analysis of ductile fracture of AA6063 aluminum alloy

  • In order to explore the ductile fracture mechanism of AA6063 aluminum alloy, a series of ductile fracture tests were carried out, and the ductile fracture morphology of AA6063 aluminum alloy specimens under different stress triaxiality was observed. The results show that the higher the stress triaxiality, the faster the nucleation, growth, and convergence of the holes, and the larger and deeper the holes. The mode of dominant ductile fracture of specimens under different stress triaxiality is also different. The fracture of notched cylindrical tensile specimens is dominated by dimple fracture, and the fracture of grooved plate tensile specimens is co-dominant by dimple fracture and shear fracture. The cylindrical torsion test fracture is mainly dominated by shear fracture and there are some dimple fracture characteristics on the surface of the specimens.
