Webbthe stress–strain curve proceeds along FG, virtually as a continuation of the curve BC. The curve EFG may be regarded as the stress–strain curve of the metal when prestrained by the amount OE. The greater the degree of prestrain, the higher the new yield point and the ﬂatter the strain-hardening curve. For a heavily prestrained WebbThe stress-strain curve can also be used to qualitatively describe and classify the material. Typical regions that can be observed in a stress-strain curve are: 1. Elastic region, 2. Yielding, 3. Strain Hardening, 4. Necking and Failure. A stress-strain curve with each region identified is shown below in . Figure 5. The

WebbAt a given value of pre-strain the measured Young’s modulus represents the tangent modulus of the stress–strain curve at that point. The repeated execution of one-shot tests at different pre-strain values ( Fig. 9.20 ) provides a curve which plots the mean value of Young’s modulus in the explored frequency range against the pre-strain.
