Structural and mechanical properties of random packings of spherocylinders: a simulation study — •Pascal Wieland and Claus Heussinger — Georg-August-Universität Göttingen, Institut für Theoretische Physik

An energy-minimization technique is developed to study random packings of soft spherocylinders in the vicinity of the jamming point.

We are interested in structural and mechanical properties as a function of the aspect ratio of the cylinders. In particular, we determine the average number of inter-particle contacts as well as their types (side-side, tip-side, tip-tip).

The simulation data is compared with experimental results obtained from x-ray tomography of spaghetti packings (in collaboration with C. Lewandowski and M. Schröter, also see their contribution).
