WebSep 18, 2003 · Granular matter does not flow homogeneously like a fluid when … 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 …

WebFeb 1, 2011 · This paper describes recent computer simulation studies into the rheological behavior of granular materials in the regime that lies between the quasistatic and rapid-flow regime. This investigation was prompted by studies of landslides, hopper flows and the “phase change” (i.e. the change between solidlike and fluid-like behavior) all of which … greek food burry port

WebMay 12, 2024 · We show a new trend of dense granular flow behavior above average normal stress of 0.3 MPa with weakening at high strain rate, which may be explained by shear-thinning thixotropy. Experimental results for a given shear rate at normal stresses between 0.3 and 1 MPa show a bifurcation in shear-resistance behavior.
