Abstract

The development of the non-uniform fracture layer and the effect of the non-uniform fracture on the forming process of the sheared protrusion were investigated through experiments and the finite element analysis. It was found that the non-uniform fracture occurred in the contact region between the slope of the slitting punch and the sheet due to the change of the slitting direction. In addition, the effect of the non-uniform fracture on the forming process of the sheared protrusion was investigated. Experiments involving microscopic and macroscopic observations were conducted to verify the finite element analysis of the three-stage forming process of the sheared protrusions.
