Ductile fracture experiments with locally proportional loading histories (2016, methodology): “A hybrid experimental-numerical approach is therefore often required (e.g. Mohr and Henn, 2007; Bai and Wierzbicki, 2008; Dunand and Mohr, 2010; Gruben et al., 2011; Brünig and Gerke, 2011; Lou et al., 2012, 2014; Fourmeau et al., 2013; Malcher et al., 2012).”
Experimental characterization and numerical modeling of micromechanical damage under different stress states (2013, background): “calibrate the hardening and damage parameters, is insufficient to predict ductile rupture of the material over a wide stress triaxiality range [32].”
Effect of strain rate on ductile fracture initiation in advanced high strength steel sheets: Experiments and modeling (2014, background): “The reader is referred to Lecarme et al. (2011), Malcher et al. (2012) and Lou et al. (2014) for reviews of the current literature on ductile fracture of non-AHSS materials.”
