Slow Fatigue and Highly Delayed Yielding via Shear Banding in Oscillatory Shear (2024)
Journal Article
Cochran, J. O., Callaghan, G. L., Caven, M. J., & Fielding, S. M. (2024). Slow Fatigue and Highly Delayed Yielding via Shear Banding in Oscillatory Shear. Physical Review Letters, 132(16), Article 168202. https://doi.org/10.1103/PhysRevLett.132.168202

We study theoretically the dynamical process of yielding in cyclically sheared amorphous materials, within a thermal elastoplastic model and the soft glassy rheology model. Within both models we find an initially slow accumulation, over many cycles a... Read More about Slow Fatigue and Highly Delayed Yielding via Shear Banding in Oscillatory Shear.

Constitutive model for the rheology of biological tissue (2023)
Journal Article
Fielding, S. M., Cochran, J. O., Huang, J., Bi, D., & Marchetti, M. C. (2023). Constitutive model for the rheology of biological tissue. Physical Review E, 108(4), Article L042602. https://doi.org/10.1103/PhysRevE.108.L042602

The rheology of biological tissue is key to processes such as embryo development, wound healing, and cancer metastasis. Vertex models of confluent tissue monolayers have uncovered a spontaneous liquid-solid transition tuned by cell shape; and a shear...

Shear-Driven Solidification and Nonlinear Elasticity in Epithelial Tissues (2022)
Journal Article
Huang, J., Cochran, J. O., Fielding, S. M., Marchetti, M. C., & Bi, D. (2022). Shear-Driven Solidification and Nonlinear Elasticity in Epithelial Tissues. Physical Review Letters, 128(17), https://doi.org/10.1103/physrevlett.128.178001

Biological processes, from morphogenesis to tumor invasion, spontaneously generate shear stresses inside living tissue. The mechanisms that govern the transmission of mechanical forces in epithelia and the collective response of the tissue to bulk sh...

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.
