Abstract:
With the aid of FE code MARC/Autoforge, two-roll cross-forging process was simulated, and the development of deformation and the law of metal-flow were studied. The result from the simulation is in good agreement with that of the physical simulations. The stress distribution in the work-piece and contact pressure between the work-piece and tool were also analyzed. It is discovered that in cross-forging process with only one strike of the press large lateral stretch stress exists, although the hydrostatic pressure is positively small in the center of the round.
