Simple and effective mechanical cloaking (2024)
Journal Article
Fielding, S. M. (2024). Simple and effective mechanical cloaking. Journal of the Mechanics and Physics of Solids, 192, Article 105824. https://doi.org/10.1016/j.jmps.2024.105824

We show theoretically that essentially perfect elastostatic mechanical cloaking of a circular inclusion in a homogeneous surrounding medium can be achieved by means of a simple cloak comprising three concentric annuli, each formed of a homogeneous is...

Reduced stress propagation leads to increased mechanical failure resistance in auxetic materials (2024)
Journal Article
Fielding, S. M. (2024). Reduced stress propagation leads to increased mechanical failure resistance in auxetic materials. Proceedings of the National Academy of Sciences, 121(21), Article e2312899121. https://doi.org/10.1073/pnas.2312899121

Materials with a negative Poisson ratio have the counterintuitive property of expanding laterally when they are stretched longitudinally. They are accordingly termed auxetic, from the Greek auxesis meaning to increase. Experimental studies have demon...

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.

Power law creep and delayed failure of gels and fibrous materials under stress (2024)
Journal Article
Lockwood, H. A., Agar, M. H., & Fielding, S. M. (2024). Power law creep and delayed failure of gels and fibrous materials under stress. Soft Matter, 20(11), 2474-2479. https://doi.org/10.1039/d3sm01608k

Motivated by recent experiments studying the creep and breakup of a protein gel under stress, we introduce a simple mesoscopic model for the irreversible failure of gels and fibrous materials, and demonstrate it to capture much of the phenomenology s...

Discontinuous Shear Thickening in Biological Tissue Rheology (2024)
Journal Article
Hertaeg, M. J., Fielding, S. M., & Bi, D. (2024). Discontinuous Shear Thickening in Biological Tissue Rheology. Physical Review X, 14(1), Article 011027. https://doi.org/10.1103/physrevx.14.011027

During embryonic morphogenesis, tissues undergo dramatic deformations in order to form functional organs. Similarly, in adult animals, living cells and tissues are continually subjected to forces and deformations. Therefore, the success of embryonic...
