Non-monotonic dependence of the friction coefficient on heterogeneous stiffness
, 2014 The complexity of the frictional dynamics at the microscopic scale makes difficult to identify all of its controlling parameters. Indeed, experiments on sheared elastic bodies have shown that the static friction coefficient depends on loading conditions,

Effect of Friction on Dense Suspension Flows of Hard Particles
, 2017 We use numerical simulations to study the effect of particle friction on suspension flows of non-Brownian hard particles. By systematically varying the microscopic friction coefficient $\mu_p$ and the viscous number $J$, we build a phase diagram that ...
