Shear jamming and fragility in dense suspensions
Ryohei Seto, Abhinendra Singh, Bulbul Chakraborty +2
The phenomenon of shear-induced jamming is a factor in the complex rheological behavior of dense suspensions. Such shear-jammed states are fragile, i.e., they are not stable agains…
From yielding to shear jamming in a cohesive frictional suspension
Abhinendra Singh, Sidhant Pednekar, Jaehun Chun +2
Simulations are used to study the steady shear rheology of dense suspensions of frictional particles exhibiting discontinuous shear thickening and shear jamming, in which finite-ra…
The normal yield stress
Henri de Cagny, Mina Fazilati, Mehdi Habibi +2
Normal stresses in complex fluids lead to new flow phenomena because they can be comparable to or even larger than the shear stress itself. In addition, they are of paramount impor…
A constitutive model for simple shear of dense frictional suspensions
Abhinendra Singh, Romain Mari, Morton M. Denn +1
Discrete particle simulations are used to study the shear rheology of dense, stabilized, frictional particulate suspensions in a viscous liquid, toward development of a constitutiv…
Shear and normal stress measurements in non-Brownian monodisperse and bidisperse suspensions
Chaiwut Gamonpilas, Jeffrey F. Morris, Morton M. Denn
There was an error in data reduction, resulting in incorrect values for the normal stress differences and shown in Figs. 7-10, and the corrected figures are shown here.…
Discontinuous Shear Thickening in Brownian Suspensions By Dynamic Simulation
Romain Mari, Ryohei Seto, Jeffrey F. Morris +1
Dynamic particle-scale numerical simulations are used to show that the shear thickening observed in dense colloidal, or Brownian, suspensions is of a similar nature to that observe…
