Bolt yielding
WebA torque to yield fastener ( TTY) or stretch bolt is a fastener which is torqued beyond the state of elasticity and therefore undergoes plastic deformation, causing it to become permanently elongated. [1] [2] Fastener [ edit] WebMar 7, 2015 · 1) A bolt in tension connecting two half inch plate. The strain length is very short. At rupture, the bolt might elongate 1/100th of an inch. That's probably not an issue for the structure of which the bolt is a part. 2) An angle used as a 20' cross brace in tension. The strain length is much longer. At rupture the brace might elongate 4".
