Experiments and FE-simulations of stretch flanging of DP-steels with different shear cut edge quality

ABSTRACT Dual-Phase (DP) steels are today used in the automotive industry due to its large strength to weight ratio. However, the high strength of DP-steel does have a negative impact on the general formability in sheet metal forming. Unfavourable process conditions in the press shop will, on top of this, reduce the formability of DP-steels […]
