Granular flow with cohesion
Simulation of the homogeneous plane shear dense flow: both the normal pressure and the shear rate are imposed.
The blue connecting lines denote the attractive contact forces between grains. Correlated motions point out
the formation of clusters that can break, deform and reform throughout the flow. This evolution of microstructure strongly
affects the macroscopic constitutive law.
