The influence of microstructure on the fracture toughness two industrially processed 1000 MPa dual-phase (DP) steel grades is investigated. Crack initiation and propagation resistance are evaluated by means essential work (EWF) methodology main damage mechanisms results discussed in terms proportion distribution different microstructural constituents, which assessed scanning electron microscopy...

An advanced elastic-plastic self-consistent polycrystalline model, accounting for intragranular microstructure development and evolution, is coupled with a bifurcation-based localization criterion and applied to the numerical investigation of the impact of microstructural patterns on ductility of single-phase steels. The proposed multiscale model, taking into account essential microstructural a...

The susceptibility of advanced high-strength steels (AHSS) to hydrogen embrittlement (HE) limits the broad utilization these materials for body-in-white (BIW) components. considerable decrease both ductility and toughness due local accumulation inside formed components may cause unpredictable time-delayed failure. In particular deep-drawn punched AHSS are prone absorption. This work investigate...
