Extension of a shear-controlled ductile fracture model considering the stress triaxiality and the Lode parameter (2013, methodology): “Based on various analytical and numerical studies as well as experimental observation, dozens of coupled and uncoupled ductile fracture criteria (Brozzo et al., 1972; Clift et al., 1990; Cockcroft and Latham, 1968; Gurson, 1977; LeRoy et al., 1981; Ko et al., 2007; Nielsen and Tvergaard, 2010; Oh et”
A hybrid approach for modelling of plasticity and failure behaviour of advanced high-strength steel sheets (2013, methodology): “Further modifications (Gologanu et al., 1993, 1994, 1997; Kailasam and Castaneda, 1998; Nahshon and Hutchinson, 2008; Nielsen and Tvergaard, 2009, 2010; Xue, 2008) were introduced to improve the capability of this type of model; however, they also increase the difficulty in calibrating the…”
Influence of the Lode parameter and the stress triaxiality on the failure of elasto-plastic porous materials (2012, methodology): “Following the work of Ponte Castañeda and Zaidman (1994), Kailasam and Ponte Castañeda (1998), Aravas and Ponte Castañeda (2004) and Danas and Ponte Castañeda (2009a), evolution equations are given in this section for the microstructural variables eM; f ;w1 and w2 defined in relation (5).”
Experimental characterization and numerical modeling of micromechanical damage under different stress states (2013, methodology): “This damage model is based on the Gurson–Tvergaard–Needleman theory and presents recent improvements proposed by Nahshon and Hutchinson and by Nielsen and Tvergaard so as to better predict fracture under a wide range of stress states, especially with low levels of stress triaxiality.”
Ductile fracture of aluminum 2024-T351 under proportional and non-proportional multi-axial loading: Bao–Wierzbicki results revisited (2015, background): “Ductile fracture under proportional loading has been the subject of numerous recent investigations (e.g. Gao et al., 2010; Nielsen and Tvergaard, 2010; Lecarme et al., 2011; Gruben et al., 2012; Graham et al., 2012; Lou et al., 2013; Faleskog and Barsoum, 2013; Xue et al., 2013).”

Geometric deep learning for computational mechanics Part I: Anisotropic Hyperelasticity (2020, background): “…fraction of void is related to ductile fracture (Gurson, 1977; Needleman, 1987; Zhang, Thaulow, and Ødegard, 2000; Nahshon and Hutchinson, 2008; Nielsen and Tvergaard, 2010), critical state plasticity in which porosity and over-consolidation ratio dictates the plastic dilatancy and hardening…”
