Which phenomenon occurs when applying a continuously increasing shear stress to a non-Newtonian fluid?

💡 Explanation

When shear stress increases in a dilatant fluid (shear thickening), interparticle forces increase resistance to flow, because hydroclusters form restricting movement which drastically increases viscosity. Therefore thickening results, rather than thinning, reversed flow, or decreased elasticity which involve different mechanisms under shear.
