Abstract��On the basis of DEFORM��3D simulation software, the rigid and plastic model have been established. By simulating backward extruding by a disc with a central hole for the heavy shaft forgings with different height to diameter ratio,the effect of extrusion are researched.

Key words�� height to diameter ratio backward extruding by a disc with a central hole numerical simulation
