Abstract :Drawing of twisted square section rod from round bar has been studied in this paper. The drawing force was determined via an upper bound solution based on an equivalent axisymmetric curved die. By determining the profile of the equivalent curved die, a velocity field which considered the twist of material inside the die was presented. Then, internal, shearing and frictional powers were calculated and drawing force was estimated by equating the summation of these powers with required external power. For assuring of the results of analysis, various experiments were performed for St 33 bars in diameters of 10, 8 and 6 mm to twisted square section rods with sides of 8, 6 and 5 mm, respectively. Comparison of the experimental and theoretical drawing forces showed an acceptable agreement
