Rheology of dense fiber suspensions: Origin of yield stress, shear thinning, and normal stress differences

We numerically investigated the rheology of concentrated suspensions of fibers by including hydrodynamic, noncontact conservative, and inter-fiber contact interactions. In this work, we provided the first quantitative explanation of the origin of yield stress, shear thinning, and normal stress differences in fiber suspensions by focusing on contact and noncontact contributions.
