@article{114, abstract = {We report on an investigation of the solidification of a cornstarch and water suspension during normal impact on its surface. We find that a finite time after impact, the suspension displays characteristics reminiscent of a solid, including localized stress transmission, the development of a yield stress, and some elastic energy storage. The time dependence of these characteristics depends on the thickness of the cornstarch layer, showing that the solidification is a dynamic process driven by the impacting object. These findings confirm previous speculations that rapidly applied normal stress transforms the normally fluid-like suspension into a temporarily jammed solid and draw a clear distinction between the effects of normal stress and shear stress in dense suspensions.}, author = {Waitukaitis, Scott R and Jaeger, Heinrich}, journal = {Revista Cubana de Fisica}, number = {1E}, pages = {1E31 -- 1E33}, publisher = {Universidad de La Habana}, title = {{Solidification of a cornstarch and water suspension}}, volume = {29}, year = {2012}, }
