Experimental characterization and numerical modeling of micromechanical damage under different stress states (2013, background): “[24] have proposed a new elasto-plastic model which is a function of the hydrostatic pressure and the second and third invariants of the stress deviator.”
Effect of Lode parameter on plastic flow localization after proportional loading at low stress triaxialities (2014, background): “…introduction of loading, the localization of deformation at the specimen level (necking), and the detection of the onset of fracture (e.g. Bao and Wierzbicki, 2004, Mohr and Henn, 2007, Brünig et al., 2008, Fagerholt et al., 2010, Gao et al., 2011, Dunand and Mohr, 2011a, Haltom et al., 2014).”
Computational homogenization of elasto-plastic porous metals (2012, background): “Other works concerned with the influence of the third invariant of the macroscopic stress tensor have very recently been promoted by, e.g., Hsu et al. (2009) and Gao et al. (2009, 2011).”
Experiments and modeling of anisotropic aluminum extrusions under multi-axial loading – Part II: Ductile fracture (2012, background): “Gao et al., 2009, 2011) studied the effect of the hydrostatic stress and the third invariant of deviatoric stress tensor on both plasticity and ductile fracture.”
