Rupture mechanisms in combined tension and shear—Micromechanics (2007, background): “Also, a parameter quantifying the type of stress deviator state appears to be necessary (Wierzbicki et al., 2005; Barsoum and Faleskog, 2007).”
Extension of a shear-controlled ductile fracture model considering the stress triaxiality and the Lode parameter (2013, background): “Wierzbicki et al. (2005) showed that the Tresca criterion, a special case of the Mohr–Coulomb criterion, was the most faithful failure condition with the greatest robustness among seven ductile fracture criteria.”
Identification of plastic constitutive parameters at large deformations from three dimensional displacement fields (2011, neutral): “More sophisticated experimental procedures can be employed, for instance hydraulic bulge tests [15,16], bending tests [17,18], torsion test, punch test, biaxial test [19], combined tests [20,21] etc.”
Micromechanical analysis on the influence of the Lode parameter on void growth and coalescence (2011, result): “However, it has been observed in recent experimental studies by Wierzbicki et al. (2005) and Barsoum and Faleskog (2007a) that the stress triaxiality is insufficient to characterize the stress state in ductile failure.”
