In granular mechanics, the μ(I) rheology is one model of the rheology of a granular material. The flow of a granular material is assumed to be governed by the strain rate, the pressure and shear stress, and the model attempts to connect these fields. The effective friction μ is treated as a function of the inertial number I; the name alludes to this dependence.

Development
The μ(I) rheology was developed by Jop et al. in 2006.[1][2]
Evaluation
One deficiency of the μ(I) rheology is that it does not capture the hysteretic properties of a granular material.[3]
