Journal Article
Hoyle, D., & Fielding, S. (2017). Necking after extensional filament stretching of complex fluids and soft solids. Journal of Non-Newtonian Fluid Mechanics, 247, 132-145. https://doi.org/10.1016/j.jnnfm.2017.06.009

We perform linear stability analysis and nonlinear slender filament simulations of extensional necking in complex fluids and soft solids, during the stress relaxation process following an interrupted strain ramp. We start by deriving analytical crite... Read More about Necking after extensional filament stretching of complex fluids and soft solids.

Age-Dependent Modes of Extensional Necking Instability in Soft Glassy Materials (2015)
Journal Article
Hoyle, D. M., & Fielding, S. M. (2015). Age-Dependent Modes of Extensional Necking Instability in Soft Glassy Materials. Physical Review Letters, 114(15), Article 158301. https://doi.org/10.1103/physrevlett.114.158301

We study the instability to necking of an initially cylindrical filament of soft glassy material subject to extensional stretching. By numerical simulation of the soft glassy rheology model and a simplified fluidity model, and by analytical predictio...
