Shear thickening and migration in granular suspensions [PDF]
Physical Review Letters, 2010 We study the emergence of shear thickening in dense suspensions of non-Brownian particles. We combine local velocity and concentration measurements using Magnetic Resonance Imaging with macroscopic rheometry experiments.

Shear-thickening and entropy-driven reentrance [PDF]
Physical Review Letters, 2005 We discuss a generic mechanism for shear-thickening analogous to entropy-driven phase reentrance. We implement it in the context of non-relaxational mean-field glassy systems: although very simple, the microscopic models we study present a dynamical ...

Vibration Characteristics of Shear Thickening Fluid-Based Sandwich Structures
Advances in Polymer Technology, 2022 The vibration attenuation mechanism of shear thickening fluid- (STF-) filled sandwich structures was investigated in this study. Structural equivalent damping, stiffness, and mass increased simultaneously with the increase in the volume fraction of shear

Tunable shear thickening in suspensions. [PDF]
Proc Natl Acad Sci U S A, 2016 SignificanceWhen a concentrated suspension is strained, its viscosity can increase radically. This behavior, known as shear thickening, can be very useful to technological applications or highly problematic in industrial processes. Suspension flow properties are typically specified at the formulation stage, meaning that they are fixed in advance rather

Design and mechanical analysis of shear thickening fluid/polyurethane composite sandwich [PDF]
MATEC Web of Conferences, 2023 In this paper, high density rigid polyurethane foam is used as sandwich skeleton and shear thickening fluid as material core. A shear thickening fluid/polyurethane sandwich structure with light impact resistance was designed and fabricated.

Jamming Distance Dictates Colloidal Shear Thickening [PDF]
Physical Review Letters, 2021 We report experimental and computational observations of dynamic contact networks for colloidal suspensions undergoing shear thickening. The dense suspensions are comprised of sterically stabilized poly(methyl methacrylate) hard sphere colloids that are spherically symmetric and have varied surface roughness. Confocal rheometry and dissipative particle

Shear thickening fluids and their applications
Materials & Design, 2022 Shear thickening fluids (STFs) are a new type of nanosuspension, which are formed by dispersing micro and nanoparticles in a dispersant. STFs are easily deformed under the action of a low shear rate.

Scaling Analysis of Shear Thickening Suspensions
Frontiers in Physics, 2022 Dense suspensions of particles in viscous liquid often demonstrate the striking phenomenon of abrupt shear thickening, where their viscosity increases strongly with increase of the imposed stress or shear rate. In this work, discrete-particle simulations

Shear-Thickening Composites for On-Demand Rebound Performance and Softness
Inventions, 2020 For footwear insoles, high rebound performance is required in some instances such as for running, while softness for comfort is of higher importance during normal walking and standing to minimize high stress.
