High-velocity compaction of a two-dimensional assembly of spherical particles is numerically studied using discrete element simulation. Three particular cases are investigated including closely packed hexagonal assembly, loosely packed random assembly and a non-homogenous assembly of different size and material particles. Primary interest is concerned with linking the particles deformation with the elasto-plastic shock wave. Simulation results yield information on particles deformation during shock propagation and change in overall particles compaction with the velocity of the hammer. The force exerted by particles on the container walls and rearrangement of the loosely packed particles during dynamic loading are also investigated. The effects of presence of friction and adhesion on both overall particles deformation and compaction process are also simulated.
