Examination of Springback in Sheet Metal Forming by Finite Element Method (original) (raw)

Sheet metal deformation is widely used in automotive industry. Nowadays the automakers try to reduce the weight of the cars by using high strength steel. The disadvantage of the high strength steel is its significant springback effect. One of the aims of this study is to utilize the springback compensation algorithm of the commercial software during the drawing simulation process. In this paper, we discuss how the sheet metal deformation was simulated by using DYNAFORM V5.5 software. The results of the simulations were compared with producers’ experience. The geometrical data of the simulated parts were provided in “.iges” file format by producers of machine components. The model prepared for the simulation was developed as a system of die, punch, addendum, binder, and blank. After sheet plastic forming analysis was done, springback was performed. LS-DYNA software was used as a solver in the simulations.
