Discrete-mechanical approach to granular media
Abstract
Discrete-mechanical approach to granular media is summarized in this paper. First the graph representation of a granular assembly is explained and the importance of duality between particle-graph and void-graph is emphasized. The discrete-mechanical quantities for granular media are introduced and their relationship and die meaning of void quantities are explained. It is shown that the fundamental matrices which connect discrete-mechanical quantities play an important role and they are discretized form of Schaefer's operator. In the last part, the formulation of constitutive relation and its future direction are discussed.
