Dynamic Shear Jamming

nature_web-01

A suspension of cornstarch particles in water is liquid-like when perturbed lightly, but turns into a jammed solid when sheared strongly. We explored how this solidification propagates through the material using high-speed imaging after applying a sudden deformation. This jamming transition is related to, but distinct from the shear-thickening that this material also exhibits.
Our findings are published in Nature:
