Computer-aided modeling tools for forging process feasibility studies

Equations were developed to express stress distributions for a variety of deformation configurations. Strain equations were developed as they apply to forged workpieces, as were strain rate equations. The flow stress equation was introduced. The shear criterion was established to minimize the amount of energy that deforming metal flow consumes. An equation was developed relating flash width and thickness using the concept of constant volume. Force equations were developed for lateral and converging flow. From these equations, the closed-die axisymmetric forging process was simulated in two cases: constant ram speed and constant strain rate. Fortran programs were developed for both cases. Software employed to present on-screen interactive graphics was FIGARO by MEGATEK. The feasibility of producing a particular part was studied by comparing net shape, near net shape, and conventional forging/machining methods. A near net shape design with some machining was recommended as most economical.
