摘要：

This paper presents a method of obtaining an approximate solution to the velocity and stresses in the cold rolling of a thin metal strip when the roll gap is not parallel. The material is assumed to be rigid plastic, and we assume coulombic friction between the roll surface and the material. The solution is obtained by means of an asymptotic expansion in the parameter delta, which is the ratio of the strip entrance thickness to the length of the plastic region. The solution of the approximate equations at the order where the non-plane strain behavior is first encountered is obtained by means of polynomial approximations, and the resulting deviations in the velocity and stress components from their plane strain values are displayed
