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:

    You oughtn’t to yield to temptation.
    Well, somebody must, or the thing becomes absurd.
    Anthony Hope (1863–1933)

    The years-heired feature that can
    In curve and voice and eye
    Despise the human span
    Of durance—that is I;
    The eternal thing in man,
    That heeds no call to die.
    Thomas Hardy (1840–1928)
