Particle Size Effects in Flow-Stabilized Solids
Scott Lindauer, Carlos P. Ortiz, Robert Riehn +1
Flow-stabilized solids are a class of fragile matter that forms when a dense suspension of colloids accumulates against a semi-permeable barrier, for flow rates above a critical va…
Glassy dynamics of landscape evolution
Behrooz Ferdowsi, Carlos P. Ortiz, Douglas J. Jerolmack
Soil creeps imperceptibly downhill, but also fails catastrophically to create landslides. Despite the importance of these processes as hazards and in sculpting landscapes, there is…
Friction controls submerged granular flows
Juha Koivisto, Marko Korhonen, Mikko J. Alava +3
We investigate the coupling between interstitial medium and granular particles by studying the hopper flow of dry and submerged system experimentally and numerically. In accordance…
Nonaffine deformation under compression and decompression of a flow-stabilized solid
Carlos P. Ortiz, Robert Riehn, Karen E. Daniels
Understanding the particle-scale transition from elastic deformation to plastic flow is central to making predictions about the bulk material properties and response of disordered…
Rheology of sediment transported by a laminar flow
M. Houssais, C. P. Ortiz, D. J. Durian +1
Understanding the dynamics of fluid-driven sediment transport remains challenging, as it is an intermediate region between a granular material and a fluid flow. Boyer \textit{et al…
Nonlinear Elasticity of Flow-Stabilized Solids
Carlos P. Ortiz, Karen E. Daniels, Robert Riehn
Thermal fluctuations, geometric exclusion, and external driving all govern the mechanical response of dense particulate suspensions. Here, we measure the stress-strain response of…
Flow-Driven Formation of Solid-like Microsphere Heaps
Carlos P. Ortiz, Robert Riehn, Karen E. Daniels
We observe the formation of heaps of repulsive microspheres, created by flowing a colloidal microsphere suspension towards a flat-topped ridge placed within a quasi two-dimensional…
