Bingham plastic model equation
WebApr 10, 2024 · The main goal of this article is to review various results and methods concerning the numerical simulation of Bingham visco-plastic flow; these results have been obtained from the early 1970s to now. WebDec 23, 2024 · The Bingham Plastic model is the simplest. It introduces a nonzero shear stress at zero shear rate: Me = T/y = Mp + /y where mp is dubbed the plastic viscosity and t0 the yield stress, that is, the stress required to initiate flow. mp, is analogous to m in the Newtonian equation.
