There is considerable experimental evidence that the classical no-slip boundary condition of
fluid mechanics is not always a valid assumption for the flow of high molecular weight …

We briefly review the recent advances in the rheology of entangled polymers and identify
emerging research trends and outstanding challenges, especially with respect to branched …

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 …

The recent particle-tracking velocimetric (PTV) observations revealed that well-entangled
polymer solutions and melts tend to either exhibit wall slip or assume an inhomogeneous …

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 …

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 …

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 …

Friction is an important phenomenon that can dominate the resulting product geometry of
thermoplastic composites upon forming. A model was developed that predicts the friction …

This work studies the most basic and important behavior of entangled linear polymer melts
in sudden large shear deformations. In particular, melt elasticity resulting from the large step …

Using self-designed particle visualization instrumentation, startup shear and step-strain tests
were conducted under a series of systematically varied rheological and geometrical …
