Concentrated solid suspensions

Explanation:
Detailed explanation-1: -In 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.
Detailed explanation-2: -Plastic flow curves do not pass through the origin but rather intersect the shearing stress axis (if the straight part of the curve is extrapolated to the axis) at a particular point referred to as the yield value. The materials that exhibit plastic flow, such materials are known as Bingham bodies.
