  • In this paper, the straightening process of a steel bar straightener is studied. The straightener carries out the bending and reverse bending process repeatedly. Plastic theory is employed for the analysis of roller-supporting-load, and the residual stress and the axial load of a steel bar are calculated by using the bending moment. The Bauschinger effect and plastic moment are calculated by using the residual stress and Swift's method respectively. It is verified from the experiments that the displacement calculated from theory makes it possible to straighten a steel bar.
