Experimental characterization and modeling of the plastic behavior of a thirdgeneration advanced high strength steel sheet
… procedure). The GursonTvergaardNeedleman (GTN) damage model was adopted to describe the fracture behavior of the Gen3 980T steel. A simple methodology for identifying the parameters of the GTN model was proposed. This calibration procedure was validated by comparing finite element …
