Grain Packing

Description

Partially crystallized packings of frictional, equal-sized spheres. A batch of approximately 200,000 beads is poured into a cylindrical container forming an initial packing in a random configuration with a volume fraction ranging from 57% to 63%. The packing is then shaken intensely for few seconds, to the point of fluidization, where a fast compaction is observed. The resulting global packing density reaches 70.5%.
