A discrete and continuum modelling approach to powder compaction is presented and discussed. The work demonstrates the ability of the discrete method to capture the compression of a ductile matrix and a matrix comprising a ductile and brittle assembly. The discrete element analysis is compared with

The discrete element method (DEM), based on a soft-sphere approach, is commonly used to simulate powder compaction. With these simulations a new macroscopic constitutive relation can be formulated. It is able to de-scribe accurately the constitutive material of powders during the cold compaction pro
