Analysis of friction among grain particles in warehousebased on finite element method
Liang you shipin ke-ji, 2019 In order to investigate the stress distribution between grain particles and the distribution of relative static friction between grain particles and silo walls, the ideal elastic-plastic constitutive relationship and Drucker-prager yield criterion were ...

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,

2D granular flows with the $\mu(I)$ rheology and side walls friction: a well balanced multilayer discretization [PDF]
, 2017 We present here numerical modelling of granular flows with the $\mu(I)$ rheology in confined channels. The contribution is twofold: (i) a model to approximate the Navier-Stokes equations with the $\mu(I)$ rheology through an asymptotic analysis.
