WebFeb 19, 2024 · A Bingham plastic fluid exhibits a yield stress which essentially means it behaves as a fluid above the yield stress and like a solid below this stress level. Some … WebAn exception to the rule is Bingham plastics, which are fluids that require a minimum stress to be applied before they flow. These are strictly non-Newtonian, but once the flow starts they behave essentially as …
