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 …

,” Phys. Fluids 25, 051703 (2013)], we showed the existence of a steady shear-banded
velocity profile for a model polymer solution with an underlying monotonic constitutive curve …

Edge fracture is a viscoelastic instability characterized by the sudden indentation of a fluid's
free surface when the fluid is subjected to a high enough shear rate. During shear …

Edge fracture, the sudden indentation of a viscoelastic fluid's free surface, often occurs when
a sufficiently strong shear is applied to the fluid, rendering rheological measurements at high …

Using simultaneous rheometric and particle-tracking velocimetric measurements, we show
that the long-time rheological states of well-entangled polymer solutions are not unique in …

Thanks to extensive observations of strain localization upon startup or after stepwise shear,
a conceptual framework for nonlinear rheology of entangled polymers appears to have …

Using high-resolution confocal rheometry, we study the shear profiles of well-entangled
DNA solutions under large-amplitude oscillatory shear in a rectilinear planar shear cell. With …

Field-theoretic modeling offers a powerful framework for the theoretical investigation of
polymeric systems, but computational study of polymer field theories has primarily been …

We use a large aspect-ratio, planar-Couette shear cell to explore the flow properties of
entangled polymer solutions, with a special focus on a long-standing problem of shear …
