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…
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…
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…
Diffusion mechanisms of localised knots along a polymer
Ralf Metzler, Walter Reisner, Robert Riehn +3
We consider the diffusive motion of a localized knot along a linear polymer chain. In particular, we derive the mean diffusion time of the knot before it escapes from the chain onc…
