Void growth and coalescence in single crystals (2010, background): “The third mode, called ‘‘necklace coalescence” (see Benzerga et al., 2004a; Gologanu et al., 2001) is less common. It has been observed to take place in rows of closely spaced voids gathering within elongated clusters. It consists of a localization process parallel to the direction of the major prin”
Modeling of Ductile Fracture: Significance of Void Coalescence (2006, unknown): “Pardoen and Hutchinson (2000, 2003), Benzerga (2002), Benzerga et al. (2004), and Kim and Gao (2005) recently implemented the GLD model into finite element analysis and their results show the computational approach based on the GLD model provides a promising tool to predict ductile material failure.”

Constitutive modeling of void shearing effect in ductile fracture of porous materials (2008, background): “Thereafter, there have been continuous efforts to modify the solution to be more accurate and realistic in capturing various aspects of the void controlled fracture, such as the yield condition [11], void nucleation [12,1], the void coalescence [13–17], the void shape effect [18–20] and the anisotro”
Micromechanically-motivated phenomenological Hosford–Coulomb model for predicting ductile fracture initiation at low stress triaxialities (2015, methodology): “At the same time, it is noted that the integral extension for non-proportional loading is conceptually problematic as discussed by Benzerga et al. (2012). We therefore emphasize that even though Eq.”
Development of the Local Approach to Fracture over the Past 25 years: Theory and Applications (2006, background): “It has been shown that the fc and δ parameters have no unique values to fit the experimental results (Zhang and Niemi, 1994, 1995; Benzerga, 2002).”
Experimental investigation of void coalescence in metallic sheets containing laser drilled holes (2008, background): “The ductile fracture process which consists of the nucleation, growth and coalescence of voids during plastic deformation has been extensively studied in the literature (see [1, 2, 3] for the void nucleation; [4, 5, 6, 7, 8, 9, 10, 11] for the void growth and [6, 12, 13, 14, 15, 16, 17, 18, 19, 20, ”
A constitutive model for plastically anisotropic solids with non-spherical voids (2010, unknown): “This has motivated the development of improved models of void coalescence (Gologanu, 1997; Gologanu et al., 2001; Benzerga et al., 1999; Benzerga, 2000; Pardoen and Hutchinson, 2000; Benzerga, 2002; Leblond and Mottet, 2008; Scheyvaerts et al., 2010).”
Ductile fracture initiation and propagation modeling using damage plasticity theory (2008, methodology): “This line of damage models often rely on the global mechanical response of some kind of microscopic representative volume structure, such as Gurson [5], Tvergaard [6], Rousselier [7] and Benzerga [8,9].”

(1998), Pardoen and Hutchinson (2000), Benzerga (2002)) involving nucleation, growth and coalescence of voids.”
Influence of the Lode parameter and the stress triaxiality on the failure of elasto-plastic porous materials (2012, methodology): “Leblond (2010) and Keralavarma and Benzerga (2010) to account for more general loading conditions (and anisotropic matrix behavior in the case of Keralavarma and Benzerga (2010)), but still make the rather strong approximation that the voids remain spheroidal in shape for general triaxial loading hi”
