Dynamic loading of a chain of non-homogenous spherical particles is presented by using the discrete element method. The dynamic response of particles is modeled by using elastic and plastic loading, elastic unloading and adhesion at contacts. Of particular interest is to study the transmission and reflection of elasto-plastic shock wave through a chain having; particles of different sizes and materials, voids between the particles and particles with/without adhesion between them. Simulation results yield information on shock propagation, particles velocity and their deformation during dynamic compaction. Particles deformation during normal and reflected shocks, particle velocity fluctuations due to voids between particles and affects of adhesion on particles separation during unloading stage are also simulated.
