Compaction of tetrahedral particles — •Max Neudecker, Stephan Herminghaus, and Matthias Schröter — Max-Planck-Institute for Dynamics and Self-Organisation, Bunsenstr. 10, 37073 Göttingen

Research in granular matter has covered packing problems of spheres extensively, but interest in non-spherical particles (ellipsoids, polyhedra) has risen only recently [1].

In this presentation, we show results of experimentally generated packings of tetrahedral particles, which are prepared by shaking. The range of mechanically stable packings is explored, from the random loose to the random close packing. We use X-Ray-tomography to analyse samples with different packing fractions and present results on their structure.
