Rolling is a regular method for production of metallic parts in various shapes and sizes. In this method, the raw material place between two rigid rolls and take the shape and size. There are two rolling methods, hot rolling and cold rolling. To achieve higher mechanical properties, and better surface quality and dimensional accuracy, the hot rolled sheets undergo the cold rolling process. The friction between the metal and rolls effects the forming process, increase the required load for forming, reduce the surface quality and increase the wear of tools. The simulation of rolling process will be helpful to improve the forming procedure and quality of products. In this research, the finite element method is used to modeling, simulation and analysis the rolling of St 37 steel sheets in normal friction plane strain conditions. Because of stress strain behavior of material during the forming process and increase of frictional stress due to forming process, the analysis of forming load between the contact surface of rolls and sheet are shown by simulation.
