Stress-strain rate relation in plug-free flow of dense granular fluids: A first-principles derivation
We derive the macroscopic stress tensor for plug-free dense granular flow, using a first-principles coarse-graining of the inter-granular forces. The derivation is based on the assumption, which defines the da Vinci Fluid model, that the inter-granular interactions are dominated by normal contact forces and solid friction. An explicit form for …
