摘要：

A computer program is developed to analyze one-dimensional elasto-plastic wave propagation in non-linear particle systems. The system is modeled by a discrete element method where the particles exhibit elastic and plastic loading and elastic unloading during compaction. The particles system is set into motion by hitting a plunger at one end while the other end is blocked. Results in form of elasto-plastic wave front propagation versus time, its peak deformations and reflection from the blocked end are shown.
