"WebbThe stress necessary to produce permanent deformation is the yield strength of the material. Some materials exhibit a sharp yield point, whereas others show a slow change in slope at the end of the elastic range. In the latter, the yield strength is conventionally defined as the stress necessary to produce a plastic strain of 0.2% (elongation). " - Offset yield stress
