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

RG Larson, PS Desai - Annual Review of Fluid Mechanics, 2015‏ - annualreviews.org
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

M Hermes, BM Guy, WCK Poon, G Poy, ME Cates… - Journal of …, 2016‏ - pubs.aip.org
We present experimental results on dense corn-starch suspensions as examples of non-

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

SQ Wang, Y Wang, S Cheng, X Li, X Zhu… - Macromolecules, 2013‏ - ACS Publications
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
whereby a material in an initially solid-like state, whether soft or hard, then yields. Major …
