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.

We shall constitute one-third and more of the ignorance and crime of the South, or one-third its intelligence and progress; we shall contribute one-third to the business and industrial prosperity of the South, or we shall prove a veritable body of death, stagnating, depressing, retarding every effort to advance the body politic.
In a well- regulated body politic this natural desire on the part of a spirited young gentleman so highly connected would be speedily recognized, but somehow William Buffy found when he came in that these were not times in which he could manage that little matter either, and this was the second indication Sir Leicester Dedlock had conveyed to him that the country was going to pieces.
But throughout creation Nature has confined the vital principle within a narrow space, in order to concentrate its power; and so it is with the body politic.
Whosoever has observed that sedate and clerical bird, the rook, may perhaps have noticed that when he wings his way homeward towards nightfall, in a sedate and clerical company, two rooks will suddenly detach themselves from the rest, will retrace their flight for some distance, and will there poise and linger; conveying to mere men the fancy that it is of some occult importance to the body politic, that this artful couple should pretend to have renounced connection with it.
One of these remarkable incidents is the execution of that instrument of government by which they formed themselves into a body politic, the day after their arrival upon the coast, and previous to their first landing.
They employed Bingham plastic theory to model the nonlinear behavior of the Magneto rheological fluid [11].
They designed a failsafe MRF damper using Bingham plastic model and the magnetic field distribution was 3D electromagnetic finite element analysis [12].
5wt% (Composition I) is not linear, as in the Bingham plastic model, but has a shape of a curve.
The flow curve is linear and corresponds to the Bingham plastic model, i.
For the commonly used Bingham plastic model, the Hedstrom technique overestimates turbulent flow friction losses because it does not take account of viscous-layer thickening.
For laminar flow in circular pipes, the analysis of the flow of a Bingham plastic is a classical case that has been known for decades; but turbulent flow, and the transition between the two types, has been more resistant to analysis.
