Dilatants
Dilatants are materials that exhibit non-Newtonian behavior, becoming thicker and more viscous when agitated or sheared. This phenomenon is known as shear thickening, where the viscosity of the material increases with the rate of shear stress applied. Dilatants typically have a higher concentration of solid particles dispersed in a liquid matrix, causing the particles to jam together under stress, leading to an increase in viscosity. Common examples of dilatants include cornstarch and water mixtures, which form a solid-like substance when pressure is applied, but return to a liquid state when left undisturbed.
