Yield Curve (physics)

In material science, the yield curve describes the behaviour of a plastic material.

In a two-dimensional stress system (i.e. given forces acting upon a material from two directions) the pliability or stiffness of the material can be plotted on a graph in the form of a yield curve. The curve expresses the failure stress, the combination of stresses at which the material yields, or cracks. The area inside the curve, accordingly, represents a safe combination of stresses for this material.The yield curve determines how much a material is elongating after yield point of the material.

Famous quotes containing the words yield and/or curve:

    Thus did he yield me in the shady night
    A wondrous and instructive light,
    Which taught me that under our feet there is,
    As o’er our heads, a place of bliss.
    Thomas Traherne (1636–1674)

    In philosophical inquiry, the human spirit, imitating the movement of the stars, must follow a curve which brings it back to its point of departure. To conclude is to close a circle.
    Charles Baudelaire (1821–1867)
