We perform particle scale simulations of suspensions submitted to shear reversal. The simulations are based on the Force Coupling Method, adapted to account for short range lubrication interactions together with direct contact forces between particles, including surface roughness, contact elasticity and solid friction. After shear reversal,...

Suspensions of non-Brownian particles display a complex rheology that originates in a subtle balance between hydrodynamic interactions and direct forces between particles, together with the so-called shear-induced microstructure. In particular, the influence of the microstructure has been qualitatively evidenced years ago in shear-reversal...
