Aging in a mean field elastoplastic model of amorphous solids (2020)
Journal Article
Parley, J. T., Fielding, S. M., & Sollich, P. (2020). Aging in a mean field elastoplastic model of amorphous solids. Physics of Fluids, 32(12), Article 127104. https://doi.org/10.1063/5.0033196

We construct a mean-field elastoplastic description of the dynamics of amorphous solids under arbitrary time-dependent perturbations, building on the work of Lin and Wyart [Phys. Rev. X 6, 011005 (2016)] for steady shear. Local stresses are driven by... Read More about Aging in a mean field elastoplastic model of amorphous solids.

Ductile and Brittle Yielding in Thermal and Athermal Amorphous Materials (2020)
Journal Article
Barlow, H. J., Cochran, J. O., & Fielding, S. M. (2020). Ductile and Brittle Yielding in Thermal and Athermal Amorphous Materials. Physical Review Letters, 125(16), Article 168003. https://doi.org/10.1103/physrevlett.125.168003

We study theoretically the yielding of sheared amorphous materials as a function of increasing levels of initial sample annealing prior to shear, in three widely used constitutive models and three widely studied annealing protocols. In thermal system... Read More about Ductile and Brittle Yielding in Thermal and Athermal Amorphous Materials.

Interplay of edge fracture and shear banding in complex fluids (2020)
Journal Article
Hemingway, E. J., & Fielding, S. M. (2020). Interplay of edge fracture and shear banding in complex fluids. Journal of Rheology, 64(5), Article 1147. https://doi.org/10.1122/8.0000086

We explore theoretically the interplay between shear banding and edge fracture in complex fluids by performing a detailed simulation study within two constitutive models: the Johnson–Segalman model and the Giesekus model. We consider separately param... Read More about Interplay of edge fracture and shear banding in complex fluids.

Elastoviscoplastic rheology and aging in a simplified soft glassy constitutive model (2020)
Journal Article
Fielding, S. M. (2020). Elastoviscoplastic rheology and aging in a simplified soft glassy constitutive model. Journal of Rheology, 64(3), Article 723. https://doi.org/10.1122/1.5140465

Yield stress fluids display a rich rheological phenomenology. Beyond the defining existence of a yield stress in the steady state flow curve, this includes, in many materials, rather flat viscoelastic spectra over many decades of frequency in small a...
