Often defined by the .002 offset method, this is the first significant point to the right of the proportional limit on a stress-strain diagram, so it cannot be reached without some degree of plastic deformation, though this is surreptitiously assumed not to be the case.
This corresponds to the upper limit of the resilience integral and, in its namesake phenomenon, which is common in steels, its namesake stress cannot be properly defined as the stress-strain relationship is sharply discontinuous at it. Often defined by the .002 offset method, this is the first significant point to the right of the proportional limit on a stress-strain diagram, so it cannot be reached without some degree of plastic deformation, though this is surreptitiously assumed not to be the case. For ten points, name this point; the approximate stress or strain after which an object undergoes irreversible deformation: phenomenologically the point at which a material "gives."
