At higher shear rates, the dilatancy peak disappears as shear thickening is spread out over a larger range of shear rates.

The shear thickening liquid is a polyethylene glycol that is "very deformable," he noted.
1], temperatures 25-60[degrees]C) have the flow index higher than 1, so they are dilatant fluids and their behavior is shear thickening.
Through ballistic, stab & laboratory testing, the mechanism of energy adsorption at ballistic rates is demonstrated to result from reversible shear thickening.

Colloids can show both shear thinning (viscosity decreases with increase in shear stress) and shear thickening (viscosity increases with increase in shear stress).
Specific developments in coated fabrics include: textiles with dirt repellency and self-cleaning attributes; textiles which change colour in response to changes of temperature or when they come into contact with acid; shear thickening fluid which stiffens to provide body armour; rubber-like fabrics which are impermeable to toxic chemicals; stain resistant fabrics; and waterproof fabrics.
1], the degradation of polymer (2), the second Newton plateau (2-4), and shear thickening behavior (4) were observed.
Tim Smith, Director, Flexible Armor Center talks about research into the formulation and use of Shear Thickening Fluids (STFs) for armor applications that began only in the last few years.
0 show Bingham plastics with a shear thickening at low shear rate, which is attributed to a long-time-relaxation mechanism, such as entanglement couplings between the high MW fraction and those associated with long-chain branches.
Typically, the suspension, when subjected to a shearing flow, may exhibit a yield stress or an extremely high viscosity at low shear rates, followed by shear thinning and even shear thickening at higher shear rates, and time-or strain-dependent behavior as well.
