The most well-known example of dense suspensions, a mixture of cornstarch and water, provides enough impact resistance to allow a person to run across its surface. In the past, this phenomenon had been linked to "shear thickening" under a steady shear state attributed to hydrodynamic interactions or granular dilation. However, neither explanation accounted for the stress scales required for a person to run on the surface. Through this research, it was discovered that the impact resistance is due to local compression of the particle matrix. This compression forces the suspension across the jamming transition and precipitates a rapidly growing solid mass. This growing solid, as a result, absorbs the impact energy. This is the first observation of such jamming front, linking nonlinear suspension dynamics in a new way to the jamming phase transition known from dry granular materials. 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5053 606 $aAmorphous substances 606 $aComplex fluids 606 $aFluids 606 $aSpectroscopy 606 $aMicroscopy 606 $aSoft and Granular Matter, Complex Fluids and Microfluidics$3https://scigraph.springernature.com/ontologies/product-market-codes/P25021 606 $aFluid- and Aerodynamics$3https://scigraph.springernature.com/ontologies/product-market-codes/P21026 606 $aSpectroscopy and Microscopy$3https://scigraph.springernature.com/ontologies/product-market-codes/P31090 615 0$aAmorphous substances. 615 0$aComplex fluids. 615 0$aFluids. 615 0$aSpectroscopy. 615 0$aMicroscopy. 615 14$aSoft and Granular Matter, Complex Fluids and Microfluidics. 615 24$aFluid- and Aerodynamics. 615 24$aSpectroscopy and Microscopy. 676 $a530.41 700 $aWaitukaitis$b Scott R$4aut$4http://id.loc.gov/vocabulary/relators/aut$0792303 906 $aBOOK 912 $a9910300418103321 996 $aImpact-Activated Solidification of Cornstarch and Water Suspensions$91771593 997 $aUNINA
