  This figures simulated a scroll forging process under rigid-die or elastic-die assumptions to reveal the die fracture occurring at the root of wrap.
  The major reason of the fracture lies in the unbalanced filling of material between the wraps. As a whole the effect of the elastic-die is negligible.
  From more detailed observation, however, we can find that a little earlier fracture occurred for the elastic-die. From this figure, the width increase of the die cavity in the left side is a little greater than that of the right side, which caused the difference in fracture time.
