Abstract
In this paper, simulation of asymmetric cold rolling is presented by using explicit analysis procedure. Effects of asymmetry due to variations in the roll angular velocity on the normal and shear stress distributions, length of the shear zones, sheet curvature, rolling force and torque discussed and optimized value for these parameters have been attained. Simulation results indicated that by increasing the roll angular velocity ratios, increase in the length of the shear zone and decrease in the amount of the pressure, force and torque would occur. In addition, it was found that increasing the length of the shear zone did not necessarily increase the sheet curvature. The sheet curvature was also depended on the plastic strain distributions and the shape factor. Numerical results of these simulations show that the optimum parameters could be found in order to reduce the rolling force and to eliminate the sheet curvature, as well.
