The effect of viscoelasticity on stress fields within polyethylene melt flow for a cross-slot and contraction-expansion slit geometry (2008)
Journal Article
Hassell, D., Auhl, D., McLeish, T., & Mackley, M. R. (2008). The effect of viscoelasticity on stress fields within polyethylene melt flow for a cross-slot and contraction-expansion slit geometry. Rheologica Acta, 47(7), 821-834. https://doi.org/10.1007/s00397-008-0261-8

The sensitivity of the principal stress difference (PSD) profiles to material viscoelasticity is demonstrated for two flow geometries using three different polyethylenes. Studies were performed using both experimental optical techniques and computati...

Molecular polymeric matter, Weissenberg, Astbury and the pleasure of being wrong (2008)
Journal Article
McLeish, T. (2008). Molecular polymeric matter, Weissenberg, Astbury and the pleasure of being wrong. Rheologica Acta, 47(5-6), 479-489. https://doi.org/10.1007/s00397-007-0226-3

The career of Karl Weissenberg began with X-ray structure studies of biopolymers. His background in scattering theory clearly affected his later approach to the measurements and modelling of the rheology of complex fluids. We show how the combination...

Emerging applications for models of molecular rheology (2008)
Journal Article
Graham, R. S., & McLeish, T. C. (2008). Emerging applications for models of molecular rheology. Journal of Non-Newtonian Fluid Mechanics, 150(1), 11-18. https://doi.org/10.1016/j.jnnfm.2007.09.004

Our understanding of the rich and complex motion of macromolecules has developed rapidly in recent years, particularly in the entangled regime. In this paper we highlight examples of research that has exploited our detailed picture of macromolecular... Read More about Emerging applications for models of molecular rheology.

New Dynamical Window onto the Landscape for Forced Protein Unfolding (2008)
Journal Article
Yew, Z., McLeish, T., & Paci, E. (2008). New Dynamical Window onto the Landscape for Forced Protein Unfolding. Physical Review Letters, 101(24), Article 248104. https://doi.org/10.1103/physrevlett.101.248104

The unfolding of a protein by the application of an external force pulling two atoms of the protein can be detected by atomic force and optical tweezers technologies as have been broadly demonstrated in the past decade. Variation of the applied force... Read More about New Dynamical Window onto the Landscape for Forced Protein Unfolding.
