Since the first publications of large amplitude oscillatory shear (LAOS) responses of
polymeric materials in the 1960s, different approaches have been developed to express …

To solve problems in polymer fluid dynamics, one needs the equations of continuity, motion,
and energy. The last two equations contain the stress tensor and the heat-flux vector for the …

The Oldroyd 8-constant model is a continuum framework containing, as special cases, many
important constitutive equations for elastic liquids. When polymeric liquids undergo large …

The physics of macromolecular orientation has been used to explain the elasticity of
polymeric liquids. Specifically, by first sculpting a rigid bead–rod likeness of the …

General rigid bead-rod theory [O. Hassager,“Kinetic theory and rheology of bead-rod models
for macromolecular solutions. II. Linear unsteady flow properties,” J. Chem. Phys. 60 (10) …

Rheologists have expectations for signatures of linear viscoelastic properties, such as
shapes of G′(ω) and G ″(ω). Medium amplitude (or asymptotically-nonlinear) oscillatory …

Oscillatory shear flow, performed at small-amplitude, interrogates polymeric liquids in their
equilibrium states. The fluid responds in sinusoidal shear stress waves whose amplitude …

In this paper, we provide a new exact framework for analyzing the most commonly measured
behaviors in large-amplitude oscillatory shear flow (LAOS), a popular flow for studying the …

One good way to explain the elasticity of a polymeric liquid is to just consider the orientation
distribution of the macromolecules. When exploring how macromolecular architecture affects …

General rigid bead-rod theory is actively used for connecting the complex viscosity of
polymeric liquids to the structure of macromolecules. Using general rigid bead-rod theory …
