Die pressing is used to produce components from loose particles. Powder compactionrnresults in a cohesive compact with a high relative density ranging from 0.5 for hard metalrnpowders to 0.9 and more for soft powders as iron. During densification, plastic deformation ofrngranular packing is the main phenomena. In order to understand densification mechanismsrnthe experimental approach is certainly the most efficient but techniques are limited andrnexpensive. Another option is to simulate densification thanks meshed discrete particles.rnDuring pressing, particles are deformed following an elastic-plastic hardening behaviourrnwhere friction acts at each contact. This work is focused on the analysis of the interactionrnbetween particles and the global response expressed in force-displacement curve duringrncompaction. The simulation of a cube made of 1455 particles and a cylinder made of 150rnparticles is presented with a particular attention on meshing and friction.
