In this study, drawbead restraining force was measured for the sheet metal through blankholder and lower die with a round drawbead with various penetration. This experimental data were used and the mathematical model calculated drawbead restraining force as a function of bead penetration was developed. Comparison of the results of mathematical model with the corresponding experimental results and PAM-STAMP model was showed in excellent agreement.
