In this paper, effect of back tension in drawing on central bursting defect is investigated using a rigid-plastic finite element method with the McClintock damage model. Central bursting defects under different back tension stress values are predicted and they are compared to reveal the effect of the back tension stress values on the central bursting defects. It is shown that back tension increases the possibility of central bursting defect.
