摘要: Abstract From a discrete-mechanical viewpoint, quantities of force and displacement for particles, contact points voids are defined their relationships explained. Extended incidence loop matrices introduced it is shown that these discrete form Schaefer's differential operators used in generalized continuum mechanics. Void newly introduced, explained void correspond to stress function incompatbility mechanics, respectively. Dualities existing graphs granular assembly also discussed.
