Compaction of confined mono-sized spherical particle systems under symmetric vibration: a suspension model

This paper presents a simulation study on the compaction of confined mono-sized spherical particle systems under symmetric vibration. In the model used, a random loose packing is confined between two fixed random granular boundary conditions and is submitted to symmetric vibrations of constant amplitude until complete transformation into a “suspension”. The granular system is then compacted by letting particles settle down until an equilibrium of minimum potential energy is reached.
