ToughSteel is a European project funded under the frame of the Research Fund for Coal and Steel (RFCS) programme. The main aim of ToughSteel is the dissemination and valorisation of fracture toughness as a material property to rationalise crack-related problems in Advanced High Strength Steels. This webinar aims to present the current methodologies to measure fracture toughness in thin sheet with a focus on the essential work of fracture paying particular attention to an industrial test case in which a correlation between physical and virtual stamping is carried out.
