Simulation of the Cold Compaction Process of a Structural PM Part

In the Metalworking Industry the design and the control of the processes have been traditionally based on the experience and, sometimes, considered as an art. The application of numerical methods reduces the costs of the design and elaboration processes and contributes to the improvement of the product quality. In this work the authors present the simulation of the cold compaction of a two-level powder metallurgical part using a commercial FEM code. The plastic behaviour has been represented by means of the Drucker-Prager/CAP model.
