“…The shape and position of drawbead and the amount of force on it are very important in terms of part quality. Samuel (2002) investigated the influence of drawbead geometry on the drawbead restraining force (DBRF) and BHF numerically and experimentally for aluminum alloy. In his study, two kinds of drawbead geometry which are square female and round female were investigated.…”

“…The drawbead imposes on the blank sheet, which moves through, a series of restraining and bending forces associated with a sequence of bending, unbending and reverse bending. This cyclic bending introduces strains and stresses, plasticity and a thickness change (Nine, 1978;Meinders et al, 1998;Samuel, 2002;Courvoisier et al, 2003). The modeling of real drawbead geometry requires a refined .…”

“…The idea of Nine's simulator construction is to separate the deformation resistance of the sheet from the frictional resistances. The change in friction conditions in the drawbead simulator is obtained by changing the angle of the roll wrapping [10,11], the lubrication conditions [10,12], the shape and dimensions of the drawbead model [13] and the drawing speed [12,13].…”
