Shear banding of complex fluids
T Divoux, MA Fardin, S Manneville… - Annual Review of Fluid …, 2016 - annualreviews.org
Even in simple geometries, many complex fluids display nontrivial flow fields, with regions
where shear is concentrated. The possibility for such shear banding has been known for …

Modeling the rheology of polymer melts and solutions
We review constitutive modeling of solutions and melts of linear polymers, focusing on
changes in rheological behavior in shear and extensional flow as the concentration …

[HTML][HTML] Unsteady flow and particle migration in dense, non-Brownian suspensions
We present experimental results on dense corn-starch suspensions as examples of non-
Brownian, nearly hard particles that undergo continuous and discontinuous shear thickening …

Criteria for shear banding in time-dependent flows of complex fluids
RL Moorcroft, SM Fielding - Physical review letters, 2013 - APS
We study theoretically the onset of shear banding in the three most common time-dependent
rheological protocols: step stress, finite strain ramp (a limit of which gives a step strain), and …

Multiple entanglements between two chains in polymer melts: an analysis of primitive paths based on Frenet trihedron
Y Ruan, Y Lu, L An, ZG Wang - Macromolecules, 2024 - ACS Publications
We propose an analysis of primitive paths for entangled polymers based on combining
energy minimization with the Frenet trihedron geometric analysis. Using this method, which …

Shear banding in time-dependent flows of polymers and wormlike micelles
RL Moorcroft, SM Fielding - Journal of Rheology, 2014 - pubs.aip.org
We study theoretically the formation of shear bands in time-dependent flows of polymeric
and wormlike micellar surfactant fluids, focussing on the protocols of step shear stress, step …

Shear banding in polymer solutions
M Cromer, MC Villet, GH Fredrickson, LG Leal - Physics of Fluids, 2013 - pubs.aip.org
The current theoretical belief is that the steady-state shear banding in viscoelastic liquids
requires a non-monotonic constitutive relationship between shear stress and shear rate …

New experiments for improved theoretical description of nonlinear rheology of entangled polymers
The present work discusses four types of new experiments that can improve the current
theoretical description of nonlinear rheology of entangled polymers. First, a slowly imposed …

Triggers and signatures of shear banding in steady and time-dependent flows
SM Fielding - Journal of Rheology, 2016 - pubs.aip.org
This précis is aimed as a practical field guide to situations in which shear banding might be
expected in complex fluids subject to an applied shear flow. Separately for several of the …

Yielding, shear banding, and brittle failure of amorphous materials
J Pollard, SM Fielding - Physical Review Research, 2022 - APS
Widespread processes in nature and technology are governed by the dynamical transition
