WebIn the Bingham plastic model, flow will not begin until the shear stress attains a minimum value, the yield stress, after which the flow is similar to that of a Newtonian fluid because the viscosity is constant and does not vary with shear rate. Pseudoplasticity, or shear thinning, is a non-Newtonian behavior that is desirable for drilling fluids.
