What is another word for a shear thickening fluid?

Dilatant liquid

what makes something a dilatant liquid?

With the rise in shear strain rate, the viscosity increases immediately.

Examples of shear thickening liquids

Corn flour mixed with a small amount of water and damp sand that firms when walking on it.

What makes something a thixotropic liquid?

When it is shaken, agitated or stressed overtime, it becomes less viscous.

Examples of thixotropic liquids

Yoghurt, ketchup that contains xanthan gum, gelatine or pectin gels, paints that are usually one coat and non-drip.

What makes something a Bingham plastic?

It behaves as a solid at low stresses but can flow as a viscous fluid at higher stresses.
