Ring rolling is widely used to produce seamless rings for critical structural components in assembly industries, such as machinery, aeronautics, energy and automotive. The complex process is characterized by high nonlinearity, unsteady and asymmetrical three-dimensional deformation, dynamic contact boundary conditions caused by the rotations of ring and rolls. A numerical model based on dynamic explicit finite element approach is proposed in this paper to simulate the process behaviors. An expanded ring has been obtained by numerical simulations with the model. Strain and stress analyses have been performed on the rolled ring.
