WebOne definition of toughness (or more specifically, fracture toughness) ... Toughness is related to the area under the stress–strain curve. The stress-strain curve measures … WebThe stress-strain curve measures toughness under gradually increasing load. Tensile toughness is measured in units of joule per cubic metre (J·m −3) in the SI system. In order to be tough, a material must be both strong and ductile. The following figure shows a typical stress-strain curve of a ductile material and a brittle material.

WebStress-strain curves are useful to understand the tensile strength of a given material. The given figure shows a stress-strain curve of a given metal. The curve from O to A is linear. In this region, the material obeys the Hooke’s Proportional limit law. In the region from A to C stress and strain are not proportional. Webpercent ( ε = 0.001) or 0.2 percent ( ε = 0. 002) and the stress-strain curve itself. The total strain at any point along the curve in Fig. 5.3 is partly plastic after yielding begins. The amount of elastic strain can be determined by unloading the specimen at some deformation, as at point A. When the load is removed, the specimen shortens by an older american racing wheels
