Polymer flooding is one of the most effective enhanced oil recovery (EOR) methods. High temperature and a high salt content in oil reservoirs significantly decrease the performance …
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) …
Fused-filament fabrication (FFF) is an extrusion-based form of three-dimensional (3D) printing for manufacturing parts rapidly. Commercially available polypropylene (PP) …

Of the many seminal contributions by Oldroyd to science and engineering, his weightiest embodies his 1958 general vision of the expected and allowable constitutive behaviors of …
In this work, we mathematically derive the conditions for which empirical rheometric relations such as the Cox–Merz rule and Gleissle mirror relationship are satisfied. We consider the …
A key open question for transient polymer networks is the molecular reason underlying their elastic stiffening and viscous thickening nonlinearities, with the two prevailing conventional …

Large-amplitude thermal excursions imposed on deeply supercooled liquids modulate the nonlinear time evolution of their structural rearrangements. The consequent aftereffects are …
The Oldroyd 8-constant continuum framework established a vision for constitutive equations for polymeric liquids—past, present, and future. In this Letter, we bridge a macromolecular …
We derive and study equations for the weakly nonlinear medium-amplitude oscillatory shear (MAOS) response of materials exhibiting time-strain separability. Results apply to …
