Abstract
In rolling of wide strip, longitudinal compressive stresses develop as a result of nonuniform deformation along the plate width, which enhance long-shape wave. Theoretical assessment of these stresses and factors affecting their magnitude and distributions are not emphasized in existing solutions, since most of the solutions are based on the assumption of plane strain along the entire width. In present investigation, a 3D model of cold rolling process of steel is simulated using the finite element method (FEM) to analyze the flow of material and stresses developed in steady-state wide strip cold rolling of plate with nonuniform thickness profile. The results show that the transition from a flat state to bad shape for specific ratio of output thickness to the width of plate occurs as a result of thickness profile changes, and it is also shown that the critical crown ratio changes in edge wave development are smaller than the middle one.
