Dynamic Vorticity Banding in Discontinuously Shear Thickening Suspensions (2018)
Journal Article
Chacko, R., Mari, R., Cates, M., & Fielding, S. (2018). Dynamic Vorticity Banding in Discontinuously Shear Thickening Suspensions. Physical Review Letters, 121(10), Article 108003. https://doi.org/10.1103/physrevlett.121.108003

It has recently been argued that steady-state vorticity bands cannot arise in shear thickening suspensions because the normal stress imbalance across the interface between the bands will set up particle migrations. In this Letter, we develop a simple... Read More about Dynamic Vorticity Banding in Discontinuously Shear Thickening Suspensions.

Shear Reversal in Dense Suspensions: The Challenge to Fabric Evolution Models from Simulation Data (2018)
Journal Article
Chacko, R. N., Mari, R., Fielding, S. M., & Cates, M. E. (2018). Shear Reversal in Dense Suspensions: The Challenge to Fabric Evolution Models from Simulation Data. Journal of Fluid Mechanics, 847, 700-734. https://doi.org/10.1017/jfm.2018.279

Dense suspensions of hard particles are important as industrial or environmental materials (e.g. fresh concrete, food, paint or mud). To date, most constitutive models developed to describe them are, explicitly or effectively, ‘fabric evolution model...

Edge-Induced Shear Banding in Entangled Polymeric Fluids (2018)
Journal Article
Hemingway, E. J., & Fielding, S. M. (2018). Edge-Induced Shear Banding in Entangled Polymeric Fluids. Physical Review Letters, 120(13), Article 138002. https://doi.org/10.1103/physrevlett.120.138002

Despite decades of research, the question of whether solutions and melts of highly entangled polymers exhibit shear banding as their steady state response to a steadily imposed shear flow remains controversial. From a theoretical viewpoint, an import... Read More about Edge-Induced Shear Banding in Entangled Polymeric Fluids.

Shear banding in large amplitude oscillatory shear (LAOStrain and LAOStress) of soft glassy materials (2018)
Journal Article
Radhakrishnan, R., & Fielding, S. M. (2018). Shear banding in large amplitude oscillatory shear (LAOStrain and LAOStress) of soft glassy materials. Journal of Rheology, 62(2), 559-576. https://doi.org/10.1122/1.5023381

We study theoretically shear banding in soft glassy materials subject to large amplitude time-periodic shear flows, considering separately the protocols of large amplitude oscillatory shear strain, large amplitude square or triangular or sawtooth str...
