WebJan 25, 2011 · Granular flow rheology can be divided into two global regimes: the elastic, which is dominated by force chains, and the inertial, which is nearly free of force chains. As the propensity of a material to form force chains should be strongly influenced by particle shape, this paper is an attempt to assess the effects of shape on flow regime transitions … WebJul 18, 2013 · Campbell, “ Granular shear flows at the elastic limit,” J.
