摘要

An elastoplastic finite element analysis has beenperformed to calculate curvature and internal stress of coldrolled strip in the roller leveler. Plane strain assumption isadopted, strip regions are divided into finite element meshes inlongitudinal and thickness directions and non-steady boundaryconditions are applied in the analysis. Results calculated withthis model are as follows: In case that tension is relatively low,effect of tension on strip curvature is relatively large. Bow ofsheet was reduced with decreasing diameter of leveler rolls.Residual stress was reduced with increasing number of leveler rolls.
