Abstract [en]

In the present investigation a finite element study is performed concerning the local contact behavior of spherical powders in unit cell arrangements of composite powder materials. In particular, die compaction of unit cells of regular body-centered cubic lattices have been studied and the numerical results are compared to previous analytical and numerical findings describing, in particular, local contact but also global behavior in composite powder compaction. The foundation for the analytical results rests on previously published results where approximate composite contact relations are derived from self-similarity considerations in a situation where the powder particles are of the same material. Results pertinent to isostatic compaction are also presented for comparative reasons. The finite element calculations are continued up to full density of solid material in the unit cells.
