Focus on simplicity and robustness of experimental technique:

? All experiments can be performed in a uniaxial testing machine
? Strains to fracture can be directly measured on specimen surface (no FEA needed)

? Localized necking criterion for arbitrary loading conditions e.g. combination of bending and membrane loading

? What if localized necking does not occur?

? Three point bending of hot stamped martensitic hat section

? Developed HC ductile fracture model accounting for (a) stress state, (b) strain rate, (c) anisotropy, and (d) loading history

? Basic version of HC model requires results from three calibration experiments only

? All calibration experiments can be performed in a uniaxial testing frame and fracture strain is directly measured using digital image correlation

? Presented SHPB technique for oscillation-free measurements at intermediate and high strain rates

? By combining the Domain of Shell-to-Solid Equivalence and HC model, ductile failure is conveniently predicted with shell finite elements
