Research on the Influence of Bending Unloading Effect on Elongation in Cold Steel Strip Tension Leveling

Abstract:

Based on the fundamental assumption of the stretch-bending straightening theory and applying the elastoplastic theory, the paper analyzes and deduces the distribution and change of stress and strain of strip in the bending springback, raising that bending unloading will increase the elongation of the neutral layer of the strip. Then, through the conditions set-up of the finite element simulation model and results of data analysis, we found the effect of different tension and bending degree on the elongation for the neutral layer of the cold strip in process of unloading, and this kind of influence is described quantitatively.
