Micromechanically-motivated phenomenological Hosford–Coulomb model for predicting ductile fracture initiation at low stress triaxialities (2015, methodology): “The presence of voids may be neglected when describing the macroscopic elasto-plastic response of sheet metal at low stress triaxialities (e.g. Dunand and Mohr (2011a)).”
A hybrid approach for modelling of plasticity and failure behaviour of advanced high-strength steel sheets (2013, background): “The prediction of the calibrated parameters on the geometries that were not involved in the calibration procedure has not been proved to be satisfactory (Bonora et al., 2005; Dunand and Mohr, 2011).”
Ductile failure modeling (2016, methodology): “Details may be found in Dunand and Mohr [98,99].”
Stress–strain curves of metallic materials and post‐necking strain hardening characterization: A review (2019, background): “It can be seen that when n=1, Equations (48) and (50) take the same form.”
Experimental characterization and numerical modeling of micromechanical damage under different stress states (2013, background): “Recently, Dunand and Mohr [41] have showed that the values of q1 = 1 and q2 = 0.”
Extension of a shear-controlled ductile fracture model considering the stress triaxiality and the Lode parameter (2013, background): “O aluminum annealed 660 F and 7075-T6 aluminum alloy (Halford and Morrow, 1962) as well as TRIP780 steel sheet (Dunand and Mohr, 2011), which indicates variation of Lode parameter sensitivity for different materials.”
