The paper proposed an enhancement to the Granular Material Point Method extending original framework for unsaturated granular materials. It discusses briefly key processes occurring during flows and gives a set of assumptions simplified analysis such with Method. Then it proposes algorithm materials shows how adjust code. Finally, presents two sets simulations involving comparing outcomes from ...

Numerical models of granular materials are useful in tribology, and can be used to predict wear friction contacts. DEM-like simulations model particles third-body, which partly debris from rubbing bodies. It has been shown that the third-body have different flow regimes, depending on their mechanical properties. Among characteristics agglomerate size seems crucial. A method based vortex analysi...
