O adelgaçamento por cisalhamento, ou pseudoplasticidade, é uma não-newtoniano comportamento onde um fluido viscosidade decreases with an increasing rate of shear stress. Many common substances, like ketchup or paint, exhibit this property. At rest, they are thick, but they flow more easily when shaken, stirred, or spread. This is often modeled by the Ostwald–de Waele power-law relationship.
