【Abstract】 Elastic-plastic and large deformation FEM is used to simulate friction distributing along the deformation area in sheet rolling and to analyze the influence that various factors lead to the friction distributing among different rolling condition. Then the variety of the following factors in various rolling conditions can be ascertained, such as the friction, neutral point, the length of contact arc and the length of forward and backward glide areas.更多还原
