Collision of Dynamic Jamming Fronts in a Dense Suspension
Olav Ro mcke, Ivo R. Peters, R. Jason Hearst
Dynamic jamming is a phenomenon whereby a dense suspension switches from a fluid-like to a solid-like state when subjected to sufficient stress and deformation. Large enough system…
Characterizing the surface texture of a dense suspension undergoing dynamic jamming
Olav Rømcke, Ivo R. Peters, R. Jason Hearst
Measurements of the surface velocity and surface texture of a freely propagating shear jamming front in a dense suspension are compared. The velocity fields are captured with parti…
Getting jammed in all directions: Dynamic shear jamming around a cylinder towed through a dense suspension
Olav Rømcke, Ivo R. Peters, R. Jason Hearst
Experimental results of towing a cylinder through a dense suspension of cornstarch and sucrose-water are presented. Focus is placed on the jamming fronts that exist in such systems…
Constitutive relations for shear fronts in shear-thickening suspensions
Endao Han, Matthieu Wyart, Ivo R. Peters +1
We study the fronts that appear when a shear-thickening suspension is submitted to a sudden driving force at a boundary. Using a quasi-one-dimensional experimental geometry, we ext…
High-speed ultrasound imaging in dense suspensions reveals impact-activated solidification due to dynamic shear jamming
Endao Han, Ivo R. Peters, Heinrich M. Jaeger
A remarkable property of dense suspensions is that they can transform from liquid-like at rest to solid-like under sudden impact. Previous work showed that this impact-induced soli…
From splashing to bouncing: the influence of viscosity on the impact of suspension droplets on a solid surface
Martin H. Klein Schaarsberg, Ivo R. Peters, Menachem Stern +3
We experimentally investigated the splashing of dense suspension droplets impacting a solid surface, extending prior work to the regime where the viscosity of the suspending liquid…
Dynamic shear jamming in dense granular suspensions under extension
Sayantan Majumdar, Ivo R. Peters, Endao Han +1
Unlike dry granular materials, a dense granular suspension like cornstarch in water can strongly resist extensional flows. At low extension rates, such a suspension behaves like a…
Dynamic jamming of iceberg-choked fjords
Ivo R. Peters, Jason M. Amundson, Ryan Cassotto +4
We investigate the dynamics of ice mélange by analyzing rapid motion recorded by a time-lapse camera and terrestrial radar during several calving events that occurred at Jakobshavn…
Quasi-2D dynamic jamming in cornstarch suspensions: visualization and force measurements
Ivo R. Peters, Heinrich M. Jaeger
We report experiments investigating jamming fronts in a floating layer of cornstarch suspension. The suspension has a packing fraction close to jamming, which dynamically turns int…
