Study on Fracture Failure Behavior of 6082 Automotive Aluminum Alloy Profile
Journal Title: Automobile Technology & Material - Year 2024, Vol 39, Issue 2
Abstract
Based on the Gissmo damage failure model, the failure parameters of 6082 automotive aluminum alloy profile were obtained by numerical parameter inverse method. The reasonability of the Gissmo damage failure model of 6082 aluminum alloy was verified by the quasi- static three- point bending test of the aluminum alloy impact beam.Firstly, the hardening curve of the 6082 material was obtained by quasi-static uniaxial tensile test, and the curve was extrapolated by Swift- Hockett- Sherby (SHS) law. Secondly, quasi- static tests (shear, uniaxial, central hole, notch, three- point bending, cupping) under various stress states were carried out, and Gissmo failure parameters were obtained by numerical inversion of test combined with simulation. Finally, the quasi-static three-point bending test of 6082 aluminum alloy impact beam was designed to verify the reasonability of Gissmo model. The test result shows that the Gissmo damage failure model of 6082 aluminum alloy proposed in this research, including hardening curve, failure strain curve, instability curve and mesh-size regulation curve, can predict the failure behavior of 6082 impact beam.
