The finite element simulation of forming processes or vehicle crash scenarios involves multiaxial loading conditions in general. Thereby, damage and failure ductile steel sheets is triggered by void growth under hydrostatic tensile elongation within a narrow band shear dominated loading. These different mechanisms are considered stress state dependent continuum model. initiation represented cri...

The ductile fracture of thin-shell structures was studied here using a localized necking model. punching experiments for unstiffened and stiffened panels were compared with numerical predictions combined model shell elements. plasticity parameters JIS G3131 SPHC steel identified by performing calibration on standard flat bars, notched tension, central hole plane strain shear specimens. beyond t...
