Sequential random packings of spheres and ellipsoids

We introduce sequential random procedures to pack polydisperse spheres and ellipsoids. For spheres, we generalize the recent study of random space‐filling bearings to a situation, where the offset varies randomly and show that it reproduces well the fractal dimension observed in real fault gouges. For ellipsoids, we show how to use variational methods to determine both translations and rotations for packing them sequentially. The algorithm considers an external gravitational field and retrieves the contact points according to the rotations and translations obtained from two variational procedures.
