Bingham Plastic

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.

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, which will not be extruded until a certain pressure is applied to the tube. It then is pushed out as a solid plug.

Famous quotes containing the words bingham and/or plastic:

    An isolated outbreak of virginity ... is a rash on the face of society. It arouses only pity from the married, and embarrassment from the single.
    —Charlotte Bingham (b. 1942)

    What a wonderful faculty is memory!—the most mysterious and inexplicable in the great riddle of life; that plastic tablet on which the Almighty registers with unerring fidelity the records of being, making it the depository of all our words, thoughts and deeds—this faithful witness against us for good or evil.
    Susanna Moodie (1803–1885)
