New finite element control has been proposed and developed to cope with large plastic flow of materials in practical forging situation; since composite triangular or tetrahedral elements are employed in the present approach, completely automatic mesh control can be available to trace the history of deformation and stress/strain states with reduction. Numerical examples are taken to demonstrate the validity and effectiveness of our developing system.
