Bingham Plastics: Heterogenous Mixtures or Compounds?

[GiTS]

Are bingham plastics always heterogenous mixtures, like mud, or are there known compounds?

 

[PerennialII]

'Atypical' applications of Bingham like material models (other than mud that is) have come across are continuum damage mechanics analyses (Bingham matrix), in which the mixture is in a sense heterogeneous, but in another not (inclusions etc. stuff in a viscoplastic metallic matrix). A related application is that of 'simple' viscoplasticity, where think the material models of Bingham kind have at least some merit (meaning in 'traditional' materials as well).

Bingham Plastics are a type of non-Newtonian fluid that exhibits both solid and liquid-like properties. They are typically composed of a polymer, such as polyethylene oxide, suspended in a solvent, such as glycerol. Therefore, they can be classified as a heterogeneous mixture.

However, there are also known compounds that can exhibit Bingham Plastic behavior. For example, some clay-water mixtures can behave as Bingham Plastics due to the presence of interparticle forces. In this case, the clay particles act as the polymer component while the water acts as the solvent.

Overall, while Bingham Plastics are commonly heterogeneous mixtures, there are also known compounds that can exhibit similar properties. The classification of Bingham Plastics depends on the specific composition and properties of the material in question.
