On the Relative Validity of Two Current Cold-Rolling Theories

Abstract

The paper compares the established cold-rolling theory of Ford, et al., with the more recent shear-plane theory. Recent experimental results obtained by the authors are used in the comparison and it is shown that, although the shear-plane theory is inherently more correct as it does not assume homogeneous compression of the strip, the effect of the usual assumption of a yield stress independent of deformation rate virtually negates any advantage in its use at present.
