摘要: Abstract In the present work a comprehensive experimental/numerical study on 6060 T6 bumper profile subjected to combined shear-compression (shear-punch test) load is carried out. A set of key plasticity and fracture parameters predict correctly mechanical response structural component required. Fracture initiation tests lab scale specimens provide sufficient data needed calibrate newly extended non-quadratic yield function Yld2000-3d isotropic Modified Mohr-Coulomb (MMC) model. The calibrated constitutive model then validated upon disk-shaped specimen. Moreover, test results are reported full-scale extruded aluminum shear-punch load. detailed FE supporting structure was built. numerical simulation outcomes demonstrate that material predicts not only global force-displacement but also local behavior at multiple initiation points. It shown various part multi-cell cross-section underwent different loading histories. Thus, in one single wide range stress triaxialities develop which requires introduce very complete
