WebbFailure load, failure strain, and tensile stiffness were measured and correlated with injury type and location. The mean failure load for the 12 specimens was 3100+/-645 N, mean … Webb6 apr. 2024 · This changes the torque-tension value of the joint by increasing the clamp load. When a fastener is undertightened to a lower clamp load, cyclical or fluctuating loads in excess of that clamp load can soon lead to fatigue. Medcalf says that undertightened fasteners undergo more external loading than expected.

A variation as high as ±35% means that at exactly the same measured torque, the tension in the one bolt could be less ...
