In this study, the three-dimensional finite element model of the UOE forming process has been established. The large deformation and complex contact during UOE forming process are simulated, and the spring back after forming is also calculated. The deformed geometries of different steps as long as distribution of the equivalent plastic strain and the force are obtained. The research is helpful in UOE forming process design and evaluating the capability of the pipe mill.
