At the conclusion of the ring-gear forging simulation, the cylindrical block (work piece) completely fills the die gap. The die gap becomes very narrow as deformation progresses and rezoning becomes necessary, as there are not enough elements and nodes in the free surface to completely fill this gap as the work piece material flows.
Equivalent Plastic Strain and Equivalent (von Mises) Stress results at the final stage (complete die fill) are plotted in the figures below.
Note: The results obtained may differ than those reported in the figures below since the Nonlinear Adaptive Region may create a different mesh than the one shown below. The aim of this tech demo is to explain the use of advanced technology in Ansys Mechanical.
