Abstract: A combined discrete element method (DEM) and finite element method (FEM) is presented. A 2D program is developing for application to mesoscale simulation of heterogeneous and homogeneous material under shock loading, and the numerical simulations are testified. The results of simulation are in agreement with those of theory, which verifies that the combined method is viable.
