Bingham pseudoplastic
WebThe materials that exhibit plastic flow, such materials are known as Bingham bodies. A Bingham body does not begin to flow until shearing stress corresponding to the yield value is exceeded. At stresses below the yield value, the substance acts as an elastic material. WebNov 17, 2024 · A Bingham Pseudoplastic fluid has a yield stress, but also decreases in viscosity as it shears at higher rates. How to Model Non-Newtonian Fluids Mathematically. Numerous models exist to capture the real behavior of non-Newtonian fluids.

Pseudoplastic flow exhibits the behavior of both Newtonian flow …
Bingham plastics require a critical shear stress to be exceeded in order to start flowing. This behaviour is usually seen in polymer/silica micro- and nanocomposites, where the formation of a silica network in the material provides a solid-like response at low shear stress. See more In rheology, shear thinning is the non-Newtonian behavior of fluids whose viscosity decreases under shear strain. It is sometimes considered synonymous for pseudo-plastic behaviour, and is usually defined as excluding See more Some authors consider shear-thinning to be a special case of thixotropic behaviour, because the recovery of the microstructure of the liquid to its initial state will always require a non-zero time. When the recovery of viscosity after disturbance is very rapid however, … See more • Shear thickening – Material in which viscosity increases with the rate of shear strain • Non-Newtonian fluid – Fluid that does not follow Newton's Law of Viscosity • Power-law fluid – Type of generalized Newtonian fluid See more 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, See more Modern paints are examples of pseudoplastic materials.
