The technologies of the numerical analysis made remarkable progress to understand the geoscience phenomena. However, in these approaches the subsurface has been modeled by a continuum medium and the finite difference method, finite element method, or boundary element method are adopted to solve the governing equations. Therefore it has been hard to treat the discontinuous phenomena. In this paper, The authors adopt the discrete element method to simulate the elastic wave propagation and also the Hopkinson bar effect. The simulation results showed this approach is quite useful for the analyzing the blasting and/or discontinuous phenomena in the subsurface.
