Abstract:
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.
Key words:
3-Roll reducing Non-linearity FEM Prediction of the product quality
