Applying GSH to a Wide Range of Experiments in Granular Media
Granular solid hydrodynamics (GSH) is a continuum-mechanical theory for
granular media, the range of which is shown in this paper. Simple, frequently
analytic solutions are related to classic observations at different shear
rates, including: (i)~static stress distribution, clogging; (ii)~elasto-plastic
motion: loading and unloading, approach to the critical state, angle of
stability and repose; (iii)~rapid dense flow: the -rheology, Bagnold
scaling and the stress minimum; (iv)~elastic waves, compaction, wide and narrow
shear band. Less conventional experiments have also been considered: shear
jamming, creep flow, visco-elastic behavior and nonlocal fluidization. With all
these phenomena ordered, related, explained and accounted for, though
frequently qualitatively, we believe that GSH may be taken as a unifying
framework, providing the appropriate macroscopic vocabulary and mindset that
help one coming to terms with the breadth of granular physics.Comment: arXiv admin note: substantial text overlap with arXiv:1207.128
