Lip Shape Behaviour of Sheet Metal in Hole Flanging Process

Pankaj Shrivastava


In this paper, the lip shape behaviour of sheet metal in hole-flanging process is studied. In this study, a numerical simulation for elasto-plastic analysis of hole-flanging process is done. The lip shape behaviour on hole-flanging process is studied under different geometrical conditions such as centre hole diameter and different punch profile radii. The results of simulations are validated with a few published experimental results.
