Constraints and vibrations in static packings of ellipsoidal particles
We numerically investigate the mechanical properties of static packings of ellipsoidal particles in 2D and 3D over a range of aspect ratio and compression $\Delta \phi$. While amorphous packings of spherical particles at jamming onset ($\Delta \phi=0$) are isostatic and possess the minimum contact number $z_{\rm iso}$ required for them …
