Abstract: Taking double-die ironing for
example, the plastic deformation behavior of the workpiece in
multidie ironing process is analysed by the rigid-plastic finite
element method (RPFEM). Considering the strain hardening of the
material, the distributions of the effective strain rate and
hydrostatic stress are obtained. Calculated results and the
effect of die angles on the deformation and ironing force are
discussed. The comparison of calculated results with those of
experiment shows a good agreement.
