Abstract

Fine, cohesive-frictional powders are the subject of this study. The behavior under isotropic compression is examined for different material properties involving, friction, rolling-resistance, and contact-adhesion. From a single simulation, the constitutive relation for the density-pressure relation can be extracted. The examined powders show an interesting behaviour: the compaction slows down for moderate stresses and then accelerates for higher pressures.
