Página 13 - Yield strength is the stress at which a material exhibits a specified limiting deviation from the proportionality of stress to strain. The deviation is expressed in terms of strain, percent offset, total extension under load, etc. Determine yield strength by one of the following methods: 13.2.1 Offset Method— To determine the yield strength by the "offset method...
