Elasto-plastic shock wave propagation in a one-dimensional assembly of spherical metal particles is presented by extending well established quasi-static compaction models. The compaction process is modeled by a discrete element method while using elastic and plastic loading, elastic unloading and adhesion at contacts with typical dynamic loading parameters. Of particular interest is to study the development of the elasto-plastic shock wave, its propagation and reflection during entire loading process. Simulation results yield information on contact behavior, velocity and deformation of particles during dynamic loading. Effects of shock wave propagation on loading parameters are also discussed. The elasto-plastic shock propagation in granular material has many practical applications including the high-velocity compaction of particulate material.
