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.
Evaluation
One deficiency of the μ(I) rheology is that it does not capture the hysteretic properties of a granular material.
