Abstract

Tension leveling is applied in metal strip production lines to improve the flatness of metal strips by a combination of tension and bending. To develop tension leveling technology, finite element (FE) analysis is increasingly used in tension leveling process design to reduce the number of trial productions and provide a deeper insight into the process. For the FE analysis of tension leveling, since the material properties affect the leveling results, a material constitutive model that can accurately describe the material behaviors during tension leveling should be applied. In our previous investigation, an advanced constitutive model was constructed for the FE analysis of tension leveling with high accuracy. Here, we report the results of an analysis on tension leveling to clarify the effect of constitutive relations on FE analysis results. Leveling mechanisms for high-strength steel strips were also clarified on the basis of FE analysis results.
