Viewing Earth's surface as a soft-matter landscape

DJ Jerolmack, KE Daniels - Nature Reviews Physics, 2019‏ - nature.com
Earth's surface is composed of a staggering diversity of particulate–fluid mixtures: dry to wet,
dilute to dense, colloidal to granular and attractive to repulsive particles. This material variety …

Power-law scaling in granular rheology across flow geometries

S Kim, K Kamrin - Physical Review Letters, 2020‏ - APS
Based on discrete element method simulations, we propose a new form of the constitutive
equation for granular flows independent of packing fraction. Rescaling the stress ratio μ by a …
