Mechanical stability of random packings of spherocylinders — •Pascal Wieland and Claus Heussinger — Georg-August-Universität Göttingen

We simulate random packings of soft, frictionless spherocylinders over a wide range of aspect ratios (10 ≤ α ≤ 80) in the vicinity of the jamming point. In our studies we focus on the stability of these packings, especially the relation between average number of contacts ⟨ Z⟩, aspect ratio α and volume fraction φ. Comparison of our results with previous works shows deviations and we try to extend the model used in previous works. The results are compared with experiments done using Spaghettinis.
