Influence of the Lode parameter and the stress triaxiality on the failure of elasto-plastic porous materials (2012, background): “…et al. (2000), Pardoen and Hutchinson (2000), Benzerga (2002), Flandi and Leblond (2005), Monchiet et al. (2007), Benzerga and Leblond (2010) and Keralavarma and Benzerga (2010) to account for more general loading conditions (and anisotropic matrix behavior in the case of Keralavarma and…”
Ductile Fracture by Void Growth to Coalescence (2010, background): “Currently, this aspect is either missing (Danas and Ponte Castañeda, 2009) or dealt with in a heuristic way (Gologanu et al., 1997; Keralavarma and Benzerga, 2010).”
Ductile failure modeling (2016, methodology): “Again, numerical assessment of both Monchiet et al.’s [46,47] and Keralavarma and Benzerga’s [26,27] criteria evidenced the quality of their predictions in spite, again, of the use of Gologanu et al.’s [20,20,22] basically “isotropic” velocity fields.”
Experiments and modeling of anisotropic aluminum extrusions under multi-axial loading – Part II: Ductile fracture (2012, background): “In Keralavarma and Benzerga (2010), a more general case is addressed where the underlying micromechanical problem considers nonaxisymmetric loading and spheroidal voids that are not aligned with the principal axes of matrix orthotropy.”
