Abstract: The phenomenology of explosive effects in hard rocks is of interest to workers in the energy field, in the defense field, and in planetary science. The salient characteristic of hard rock masses is that they are seldom massive monolithic formations, but rather are penetrated by numerous geologic discontinuities such as joint sets, faults, shears, contacts, etc. This paper summarizes applications of the Discrete Element (DE) method of analysis to simulation of the effects of explosions in hard rocks.
