Characterization of fracture loci in metal forming (2014, methodology): “A recent solution for this problem gave rise to a modification of the Gurson-Tvergaard-Needleman model to include a shear term that is related to damage growth in pure shear [28].”
Constitutive modeling of void shearing effect in ductile fracture of porous materials (2008, methodology): “A similar modification to Gurson model for shear failure was pursued by Nashon and Hutchinson recently [ 26 ].”
Ductile fracture of aluminum 2024-T351 under proportional and non-proportional multi-axial loading: Bao–Wierzbicki results revisited (2015, methodology): “In the shear-modified Gurson model proposed by Nahshon and Hutchinson (2008), the evolution of the void volume fraction is not only a function of the equivalent plastic strain, but also sensitive to the Lode number.”
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 parameter”
Application of extended Mohr–Coulomb criterion to ductile fracture (2009, background): “Attempts are currently underway to extend the void growth and coalescence model to describe shear fracture (Xue 2007; Nahshon and Hutchinson 2008 ).”

Influence of the Lode parameter and the stress triaxiality on the failure of elasto-plastic porous materials (2012, methodology): “…of the stress triaxiality, but with different Lode parameters ranging from axisymmetric tension (L ¼ þ1) to biaxial tension with axisymmetric compression (L ¼ 1), is the main advantage of the SOM model over the models of Gurson (1977), Nahshon and Hutchinson (2008) and Nielsen and Tvergaard (2010).”
Continuum Models of Ductile Fracture: A Review (2010, methodology): “The GTN model was recently modified to introduce a softening term depending on the Lode parameter (Nahshon and Hutchinson, 2008).”
