What is the Bingham Plastic Model? - Definition from Trenchlesspedia

The viscosity of a shear thickening fluid, or dilatant fluid, appears to increase when the shear rate increases. Corn starch suspended in water ("oobleck", see below) is a common example: when stirred slowly it looks milky, when stirred vigorously it feels like a very viscous liquid. A familiar example of the opposite, a shear thinning fluid, or pseudoplastic flui… WebAt shear stresses less than yield stress, Bingham plastics behave as a solid and at shear stresses higher than yield stress it behaves as a fluid. ...more. ...more.
