Jamming of frictional tetrahedra — •Max Neudecker1, Stephan Ulrich2, Stephan Herminghaus1, and Matthias Schröter1 — 1Max-Planck-Institut für Dynamik und Selbstorganisation, Bunsenstr. 10, 37073 Göttingen — 2Universität Göttingen, Institut für theoretische Physik, Friedrich-Hund-Platz 1, 37077 Göttingen
We present experimental results on the packing of polypropylene tetrahedra with 7mm side length. Analysis via X-ray-tomography allows for a detailed analysis of the radial distribution function and the number and type of geometrical contacts. We focus particularly on the dependence of these packing properties on the bulk packing fraction.
