I dont really understand why use proof of stress.(adsbygoogle = window.adsbygoogle || []).push({});

One reason I can come up with is: For materials without a clear distinct yield point, yield strength is stated as stress at which permanent deformation of 0.2% of original dimension will result. (a dictionary definition)

Other than that,why we use proof stress as a measure of yielding in the case of some materials?andhow well does it show the material's yielding behavior?
