Abstract:The distinguishing techniques of 3D FEM simulation of multi-stage forming processes were presented. A CAD integrated 3D FEM simulation system, the Forming 3, has been developed to simulate the industrial multi-stage metal forming processes. Three complicated example solutions were performed using solid modeling of the forming tools. The simulation results showed good agreement with the practical results or the experimental results.
Key words: bulk forming rigid-viscoplastic finite element method remeshing
