Why 0.2% of strain is considered while taking proof stress?

WebTensile strength is defined as a stress, which is measured as force per unit area. For some non-homogeneous materials (or for assembled components) it can be reported just as a force or as a force per unit width. WebProof stress is determined as the stress corresponding to 0.2% of strain from the stress-strain curve of the given material.
