Stress relaxation following sudden cessation of steady shearing from polymer rotarance theory
MC Pak, AJ Giacomin, MA Kanso - Physics of Fluids, 2024 - pubs.aip.org
Deriving rheological material functions from rotarance theory proceeds in two steps. We first
solve the general diffusion equation to get the polymer orientation distribution, then we …

Assigning macromolecular meaning to nonlinear continuum rheology
P Poungthong, AJ Giacomin - Physics of Fluids, 2024 - pubs.aip.org
The Oldroyd 8-constant continuum framework has yielded elegant analytical solutions for
many polymer processing flows. However, continuum frameworks are silent on …

Wire coating and melt elasticity
In modern wire coating, the polymer is dragged through a round cylindrical die. Onto this
drag flow, we superpose pressure-driven extrusion. We devote this paper to analyzing this …
