The simulation by means of finite elements of the forming processes of mechanical components is a very useful tool for their design and validation. In this work, the simulation of the compaction of a metal powder is presented. The finite element software Abaqus is used together with the modified CAM-clay plasticity model in order to represent the elastoplastic behaviour of the material. Density distributions are obtained and, therefore, the motion of the compaction punches which improve this distribution can be found. Stress distribution in the different parts of the mould can also be determined.
