Simulation of Densification in Powder Metal Forging 890413

Finite Element Method (FEM) simulation of the powder metal forging process can be a useful tool in new product or process development because the simulation provides tooling load estimates, press size requirements, preform design feasibility and allows accurate and inexpensive parametric studies of forging process variables.
Several examples of simulations using ALPID-P code are presented. Axisymmetric and plane strain simulations at several cross sections of an automotive P/M connecting rod forging indicate that die wall friction has a large effect on the densification process. Also, simulations indicate a significant die wall velocity effect on densification.
