The Bingham body is an idealized material that is considered to have an internal structure that collapses above a yield stress ss0 and above which rheological behavior is linear.
Examples are coal suspensions, latex paint, and printer's ink.
These have no yield stress, but ss increases more than linearly with sn. Under certain conditions, a p.p. could approximate either newtonian or b.p. Data taken at higher shear rates might seem to extrapolate to intersect the axis above zero as for a Bingham plastic. As a result, the curve for a dilatant fluid looks the same as for a p.p., except that it is concave upwards. Because the apparent viscosity gets greater as mixing increases, such fluids are also known as shear thickening .
