How to measure bolt elongation

WebElongation measurement method Tightening is controlled by the elongation of the bolt, generated by bolt tightening. Elongation is measured by a micrometer, ultrasonic, or an embedded gauge sensor in a bolt. The dispersion of the bolt is very small. Tightening within the elastic zone is available. The efficiency of the bolted joint is large. WebAlways use the same units when solving the elongation. To calculate break elongation, Elongation = ɛ = (ΔL/L) x 100. Elongation at Break is measured in % (% of elongation vs. initial size when ...
