Theory of nonlinear rheology and yielding of dense colloidal suspensions
| Type of Publication: | Journal article |
| URI (citable link): | http://nbn-resolving.de/urn:nbn:de:bsz:352-opus-37839 |
| Author: | Fuchs, Matthias; Cates, Michael E. |
| Year of publication: | 2002 |
| Published in: | Physical Review Letters ; 89 (2002). - 248304 |
| DOI (citable link): | https://dx.doi.org/10.1103/PhysRevLett.89.248304 |
| Summary: |
A first-principles approach to the nonlinear flow of dense suspensions is presented which captures shear thinning of colloidal fluids and dynamical yielding of colloidal glasses. The advection of density fluctuations plays a central role, suppressing the caging of particles and speeding up structural relaxation. A mode coupling approach is developed to explore these effects.
