img52.chem17.comNOTE 2 In order to differentiate from the true stress related to the actual cross-section of the specimen, this stress is frequently called “engineering stress” 3.6.1 stress at yield σy stress at the yield strain NOTE 1 It is expressed in megapascals (MPa). NOTE 2 It may be less than the maximum attainable stress (see Figure 1, curves b and c)

aelabs.gatech.eduThe true stress and true strain can be evaluated from the engineering quantities under a constant material volume assumption. Assuming a constant volume, such that A 0 L 0 = AL, we can find the ratio !"! =$ $" =$"%& $" =1+) By combining the area ratio above with the expression for engineering stress, Eq. (1), the true stress is given by: s ...

courses.washington.eduthe stress-strain curves just discussed, using engineering quantities, are fictitious in the sense that the σ and ε are based on areas and lengths that no longer exist at the time of measurement. To correct this situation true stress ( σ T) and true strain (εT) quantities are used. The quantities are defined as: σ T = P A i (5.7)
