The Role of Hydrogen Bridging Bonds in the Shear-Thickening and Jamming of Dense Suspensions
Hojin Kim, Samantha M. Livermore, Yongjin Shin +1
Strong shear thickening and jamming in dense suspensions are driven by friction as particles are sheared into contact. Control over these frictional interactions can be achieved vi…
Constraint ratio controls viscosity in shear thickening suspensions
Qinghao Mao, Michael van der Naald, Abhinendra Singh +1
The dramatic viscosity increase observed in dense suspensions under shear poses a major challenge in our understanding of how microscopic contact mechanics translate into macroscop…
Fracture and failure of shear-jammed dense suspensions under impact
Malcolm Slutzky, Alice Pelosse, Michael van der Naald +1
Impacted with sufficiently large stress, a dense, initially liquid-like suspension can be forced into a solid-like state through the process of shear jamming. While the onset of sh…
Dense suspensions as trainable rheological metafluids
Hojin Kim, Samantha M. Livermore, Stuart J. Rowan +1
Memory-forming properties introduce a new paradigm to the design of adaptive materials. In dense suspensions, an adaptive response is enabled by non-Newtonian rheology; however, ty…
On the addition of micron-size intruders in a shear-thickening suspension of nanoparticles
Alice Pelosse, Heinrich M. Jaeger
This study investigates the rheological behavior of shear-thickening suspensions made of different types of nanoparticles upon the addition of large intruders referred to as granul…
Shear thickening inside elastic open-cell foams under dynamic compression
Samantha M. Livermore, Alice Pelosse, Michael van der Naald +3
We measure the response of open-cell polyurethane foams filled with a dense suspension of fumed silica particles in polyethylene glycol at compression speeds spanning several order…
