shear-thinning and shear-thickening fluids

Shear-thinning fluids, also known as pseudoplastic fluids, are substances that become less viscous (thinner) as the shear rate or stress applied to them increases. This means that they flow more easily when subjected to higher forces or forces that change rapidly. On the other hand, shear-thickening fluids, also called dilatant fluids, are substances that become more viscous (thicker) as the shear rate or stress applied to them increases. Their flow resistance increases with higher forces or forces that change rapidly, making them more difficult to deform or flow.
