Bingham plastic fluid examples
WebThe Bingham plastic model describes the flow characteristics of different kinds of mud and is described mathematically as: T - shear stress, γ - shear rate, YP - yield point and PV - plastic viscosity. Fluids that obey this model are called Bingham plastic fluids. PV should be low by minimizing colloidal solids to enable fast drilling while YP ... WebIt can be described mathematically as follows: τ = YP + PV (γ), where τ = shear stress γ = shear rate YP = yield point PV = plastic viscosity. Fluids obeying this model are called Bingham plastic fluids and exhibit a linear shear - stress, shear-rate behavior after an initial shear stress threshold has been reached.

In materials science, a Bingham plastic is a viscoplastic material that behaves as a rigid body at low stresses but flows as a viscous fluid at high stress. It is named after Eugene C. Bingham who proposed its mathematical form. It is used as a common mathematical model of mud flow in drilling engineering, and in … See more Figure 1 shows a graph of the behaviour of an ordinary viscous (or Newtonian) fluid in red, for example in a pipe. If the pressure at one end of a pipe is increased this produces a stress on the fluid tending to make it move … See more The material is an elastic solid for shear stress $${\displaystyle \tau }$$, less than a critical value $${\displaystyle \tau _{0}}$$.
