Simulation of periodic mono-sized hard sphere systems under different vibration conditions and resulting compaction

This paper presents a simulation study of confined periodic mono-sized hard sphere systems under different vibration conditions and their influence on the final compaction. An initial random loose packing is submitted to a series of vibration cycles allowing to transform it into a “suspension” in which a given proportion of particles have the possibility to vibrate. This “suspension” is then let to settle down and brought to a new denser packing. Different random local rules are used for the simulation of the displacements of particles during vibration.
