Flow properties (i.e. rheology) of suspensions depend upon constituent phases and interactions between them. For this kind of materials, stress has multiple origins: contact between particles, fluid flow and fluid-particles interactions.In this work, a new lubricated contact model has been developed and validated on several 2-particles test cases.This model regularizes singularity at contact, and takes care of very small gaps between particles. The numerical scheme developed ensure unconditional stability on time integration.Especially, this model is able to simulate two perfectly smooth particles.This model has been introduced into a DEM formulation and used to simulate simple shear experiments on suspensions. Flow behaviours agrees accoun...
