Abstract

The cup drawing process of sheet takes an important place in forming metals. The traditional techniques of tool design for sheet forming operations used in industry are experimental and expensive methods. Prediction of the forming results, determination of the punching force, blank holder forces and the thickness distribution of the sheet metal will decrease the production cost and time of the material to be formed. In this project, cup drawing simulation has been presented with finite element method. The entire production step has been simulated by ANSYS 15.0 software under axisymmetric conditions with nonlinear Transient dynamic analysis. Radial, axial, hoop and Von Mises stress patterns have been simulated for critical load conditions. A rigorous analysis of Von Mises stress has been performed to track the yield behavior of blank. Contact behavior was also observed. Simulated Punch force was compared with experimental values for different travel intervals.
