non-Newtonian fluid
fluid that does not follow Newton's Law of Viscosity, viscosity (the measure of a fluid's ability to resist gradual deformation by shear or tensile stresses) of non-Newtonian fluids is dependent on shear rate or shear rate history
Bingham plastic
material that behaves as a rigid body at low stresses but flows as a viscous fluid at high stress
power-law fluid
physical law
quicksand
colloid hydrogel consisting of fine granular material, clay, and water
