A determination method for redrawing ratios has been proposed by analyzing the redrawing process of cylindrical shells from flat circular blanks using an elementary theory of plasticity. These redrawing ratios were calculated using a criterion based on the reduction of the maximum deep drawing energy. Variation of redrawing ratio with profile radius, blank thickness, frictional force, blankholder load and strain-hardening exponent were obtained using a developed computer program aimed at rationalizing, planning and simulating the redrawing process. It is shown that the maximum deep drawing energy decreased about 10-40%, comparing the predicted drawing energy by the usual determination method for the redrawing ratios.
