Springback is a common phenomenon in sheet metal forming, caused by the elastic redistribution of the internal stresses during unloading. The aim of this search is to investigate the wave of material parameters on the results of forming and springback of sheet metal. A finite element model of cylinder bending benchmark of NUMISHEET’2002 was proposed firstly to simulate bending and springback with contact evolution between tools and blank based on static implicit method. The simulation results agree well with the experiment. Then the effects of the wave of material parameters on forming and springback results are investigated using orthogonal design simulation. Eight factors are investigated with the orthogonal label. The results show the factors have different effects on both the forming and springback. And the significance of the factors is shown through direct analysis of the results.
