Abstract—Until about mid 60's, the analysis of forging processes was based on analytical methods like slab method, slip line method and upper bound method without the help of computerization. Gradually it shifted to computerization by the arrival of digital computers, thereby accuracy and efficiency of such analysis increased. The Finite Element Numerical methods of analysis of bulk metal forming processes is increasingly applied to analyze forming defects, predict and optimize variables and to predict stress, strain damage in dies and workpiece for preventing premature die-failure & forging defects. These tools are not expert systems and do not have any intelligence built-in. They only give solution for 'what-if' analysis. FEM tools will have to be used by expert designers of processes. FEM will not automatically give the answers to the problems. The Finite Element Numerical methods of analysis can be done by Finite Element Method (FEM) & Finite Difference Method (FDM). Simulation study on DEFORM is based on FEM and provides an approximate but acceptable analysis of Forging process constrains.
