摘　　要：The 3─roll reducing processes are simulated and predicted by using 3─D elastic─plastic large strain FEM on the PC / 386 computer.The displacement field and flow field of workpiece deformation are given. The internal angle defects of the seamless tube are studied in detail during 3─roll reducing.the predictions of the forming product quality and technology parameter are realized by means of PC / 386 computer.The 3─roll reducing processes are simulated and predicted by using 3─D elastic─plastic large strain FEM on the PC / 386 computer.The displacement field and flow field of workpiece deformation are given.
