Abstract
The edge-fracture-tensile-test is an innovative examination method, which offers the possibility to characterise high strength steels with respect to edge crack sensitivity. Manufacturing processes, such as expansion and stretch flanging, which generate an uniaxial tensile stress on the components shear cut edge, lead to edge fracture. In particular, deformation and material damage of the component’s edge, caused by the shear cutting process, reduce the residual formability and prefer edge fracture initiation. A modular shear cutting tool generates edge-fracture-tensile-samples with different shear cutting process parameters. The edge-fracture-tensile-test investigates one-sided shear cut edge-fracturetensile-tensile-samples with regard to the residual formability of the shear cut edge.
