WebbFor bolted joints without a preload shear, stress is calculated like bearing stress: force over area. Like bearing stress, it is also an average stress and the maximum shear will be … 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.
