Prediction of spread, pressure distribution and roll force ...

Abstract. The ring rolling process involves 3D non-steady flow and continuous change of radius and thickness of the ring workpiece. In this study, a commercial FEM-code that is especially tailored to ring rolling process, SHAPE-RR™, is used to predict spread, pressure distribution and roll force in plain and T-shaped ring rolling processes.
