The yield point R e (yield strength) is a material characteristic value and is determined using tensile testing (eg standard series ISO 62 (for metallic materials) or standard series ISO 527 (for plastics and composites)) The yield point is specified in MPa (megapascal) or N/mm² Often an upper yield point R eH and a lower yield point R eL can be determinedThe yield strength of a bolt can be defined as the tensile force that will produce a certain amount of permanent deformation within a specific fastener In many (but not all) bolting situations, it's important not to tension a bolt past its yield strength, because it no longer retains its original size and shape and ultimately its performanceThe yield strength or yield point of the material is defined as the stress at which a material begins to deform plastically Prior to the yield point the material will deform elastically and will return to its original shape when the applied stress is removed Ultimate Strength Yield Strength En
