Experimental and numerical investigation for ductile fracture of Al-alloy 5052 using modified Rousselier model

► We propose a modified Rousselier model by incorporating the extended damage evolution model of Nahshon and Hutchinson. ► The model parameters were calibrated by an FE based inverse method with smooth and notched round bars tensile tests. ► The model’s predictive ability in shear was improved by th...
