Time scales in shear banding of wormlike micelles
... Shear banding involves spatial inhomogeneity and temporal dynamics. We use light polar- ization to probe the spatial inhomogeneity and its dynamics, and rheology to measure the time evolution of the total ...

Transient shear banding in entangled polymers: a study using the Rolie-Poly model
... inhomogeneous shear flow occurs in entangled polymer solutions, both as steady state shear banding and transiently after a large step strain or during startup to a steady uniform shear ...

Effects of nonlocal stress on the determination of shear banding flow
... In this paper, we first present numerical results for the modified Johnson-Segalman (JS) model, as a con- crete example of stress selection in a non-local model that has been well-studied in local form by many work- ers ...

Tracking of shear bands in an antiplane shear model
... When the material reaches a critical value of loading, shear banding occurs. While the overall defor- mation is described by a hyperbolic system of equations, hyperbolicity is lost at the points when ...

Classical XY model with conserved angular momentum is an archetypal non-Newtonian fluid
... So the approximate theory reproduces the observed uniform states at high µ, a continuous transition (inflec- tion in Fig. 4a) to shear-banding on decreasing µ, and first-order “freezing” (to solid-fluid or ...
