WebIt can be described mathematically as follows: PV = plastic viscosity. Fluids obeying this model are called Bingham plastic fluids and exhibit a linear shear - stress, shear-rate behavior after an initial shear stress threshold has been reached. Plastic viscosity (PV) is the slope of the line and yield point (YP) is the threshold stress. 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.
