Abstract: Based on large deformation elastic-plastic finite element method, utilising MARC software for 3D simulation of the tube while being out of shape, this paper analyses longitudinal strain of the tube in the course of roll shaping. Influence of different forming parameters such as the forming speed, the material properties and the friction coefficient have also been parametrically studied. The simulation results show that increasing the roll velocity, the material yield limit the longitudinal strain reduces. But increasing the friction coefficient, work-hardened material, inter-stand distances increase the longitudinal strain. This leads to a better insight and an efficient design for the complicated technological roll-forming process. The simulation of the tube shows that the method is suitable for the whole process simulation of cold roll forming.
