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:
“Do you really think, Arthur, that it is weakness that yields to temptation? I tell you that there are terrible temptations that it requires strength, strength and courage, to yield to.”
—Oscar Wilde (1854–1900)
“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)
