Bingham plastic
Bingham plastic[′biŋ·əm ‚plas·tik] (fluid mechanics) A non-Newtonian fluid exhibiting a yield stress which must be exceeded before flow starts; thereafter the rate of shear versus shear stress curve is linear. Bingham plastic
Bing·ham plas·tic (bing'ăm), a material that, in the idealized case, does not flow until a critical stress (yield stress) is exceeded, and then flows at a rate proportional to the excess of stress over the yield stress; real materials probably only approach this ideal model.Bingham, E.C., U.S. chemist, 1878-1945. Bingham flow - the flow characteristics exhibited by a Bingham plastic.Bingham model - a model representing the flow behavior of a Bingham plastic, in the idealized case.Bingham plastic - a material that, in the idealized case, does not flow until a critical stress (yield stress) is exceeded, and then flows at a rate proportional to the excess of stress over the yield stress. |
