Weba material that, in the idealized case, does not flow until a critical stress (yield stress) is exceeded, and then flows at a rate proportional to the excess of stress over the … WebIn contrast to a Bingham fluid, a pseudoplastic fluid is a fluid that increases viscosity as force is applied. A typical example is a suspension of cornstarch in water with a concentration of one to one. This cornstarch behaves like water when no force is applied; however, it is solidified as force is applied.

Though the exact cause of shear thinning is not fully understood, it is widely regarded to be the effect of small structural changes within the fluid, such that microscale geometries within the fluid rearrange to facilitate shearing. In colloid systems, phase separation during flow leads to shear thinning. In polymer systems such as polymer melts and solutions, shear thinning is caused by th… WebSep 2, 2024 · Concept of Bingham Bodies. A Bingham plastic is a substance that is known as viscoplastic. They behave like a rigid body under low stress but flow like fluid under high loads. Its mathematical form was invented by Eugene C. Bingham. It is therefore named after him. It is generally used in drilling engineering and slurry handling. campbell soup shoes
