On the local contact behaviour in regular lattices of composite powders

The local contact behaviour of composite powders arranged in regular lattices has been investigated in this study with the finite element method. Numerical results related to isostatic and die compaction of unit cells of simple cubic and body-centered cubic lattices have been compared to previous analytical and numerical findings describing in particular local but also global contact at powder compaction. The finite element calculations are continued up to full density of solid material in the unit cells.
