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…
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…
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…
Shear thickening in suspensions of particles with dynamic brush layers
Hojin Kim, Michael van der Naald, Finn A. Braaten +3
Control of frictional interactions among liquid-suspended particles has led to tunable, strikingly non-Newtonian rheology via the formation of strong flow constraints as particles…
