Abstract In this paper,drawing tube without plug is predicted by means of 3-D elasticplastic finite element method,some theory models of 3-D finite element are established. The distributions of the field variations are given. The new friction layer theory is applied and nonsteady and steady deformation are studied.The movement figures of the workpiece forming processes are drawn on the computer LEO/486.
