Bingham plastic fluid example

WebJul 1, 2024 · The flow of a Bingham plastic fluid is described using a model where the material behaves as a solid when the shear stress magnitude in the material τ → is lower than a given yield stress τ 0. The material behaves as a liquid when the stress in the material is higher than that yield stress. Eq.
