A finite element model suited to the nature of the process of tube spinning has been built and the deformation field of the process has been simulated by the 3D rigid-plastic FEM (finite element method) in this paper. The distributions of stress and strain rate of the deformation field are obtained. The results of the simulation can well explain the enlarged diameter, the reduced diameter, the reflection of the generatrices and wave, etc., and agree well with the experimental results, (C) 2001 Elsevier Science B.V.
