DOI: 10.1016/j.jmatprotec.2018.07.032
Abstract: Abstract The Gurson-Tvergaard-Needleman (GTN) models are effective to predict damage evolution and ductile fracture during plastic deformation, while the existing modified GTN models mainly focus on the range of stress triaxiality between −1/3 η η read more here.
