Bingham plastic

Mayonnaise is a Bingham plastic. The surface has ridges and peaks because Bingham plastics mimic solids under low shear stresses.

In materials science, a Bingham plastic is a viscoplastic material that behaves as a rigid body at low stresses but flows as a viscous fluid at high stress. It is named after Eugene C. Bingham who proposed its mathematical form.[1]

It is used as a common mathematical model of mud flow in drilling engineering, and in the handling of slurries. A common example is toothpaste,[2] which will not be extruded until a certain pressure is applied to the tube. It is then pushed out as a relatively coherent plug.
