This paper presents a study of the centripetal packing of mono-sized spherical particles simulated by means of the … granular dynamic or discrete element method. A packing is formed by imposing an assumed centripetal force on particles randomly … particles including transient forces and trajectory is traced in the present simulation. Structural properties, such as packing …

The percolation of small particles through a periodic random loose packing of large beads is studied numerically with … the Distinct Element Method. The representativity of periodic mono-sized sphere packing of varying system size was first … medium. The results show that a periodic packing of size as low as 4-grain diameters gives a reasonable representation of the …

conditions and their influence on the final compaction. An initial random loose packing is submitted to a series of vibration …. This “suspension” is then let to settle down and brought to a new denser packing. Different random local rules are used for …
