Summary:

Draw beads are commonly used in stamping operations to control sheet metal flow. The amount of sheet metal flow, or called draw-in amount, is an important index that controls the formability and quality of sheet metal parts. Numerical simulation of sheet metal forming processes is widely adopted. The draw-in map obtained through simulation serves as a guideline for successful die tryout and robust stamping. This study addresses some issues of using draw bead in simulations such as the calculation of draw bead holding and pulling forces, the thinning effect of real draw bead on draw-in amount, the adjustment of math based draw-in amount, the feasibility of using draw bead geometry in simulation, and the effect of draw bead location and configuration on sidewall curl
