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 WebIt turns out that we can get the energy of elasticity by taking the area under the curve of the stress-strain curve. That area has been highlighted in the figure below, which is the area under the curve from the origin to the yield strength. ... and also have a small toughness. So, a large toughness (metals) is obtained by having a high tensile ...
