Tensile Stress Evolution Outside Deformation Zone of Cold Rolled Strip

To determine the exact distribution of tensile stress in a cold rolled strip, evolution caused by lateral uneven velocity outside deformation zone strip is examined. The finite difference method employed to solve problem. Different factors, including width and form amplitude initial on evolution, are analyzed. On one hand, improve calculation speed, “Gaussian” curve proposed fit results calculated method. Simulation show that fitting equation good agreement with obtained other verify exactness model, an experiment conducted, comparison between experimental values discussed.
