WebJoint stiffness factor1) Cm=kb/ (kb+km) 1) For simplicity, the clamped materials are frequently assumed to have a stiffness of three times the bolt stiffness, which results in a joint stiffness factor of C m =1/4. With C m =1/4, it follows that only one fourth of the applied load P is taken by the bolt. www.tribology-abc.com WebStiffness measurements of the test system were found to show only small changes with hole wear and fastener rocking (using shadow moire techniques) also showed only small changes with hole wear. Ultrasonic C-scanning methods were used to map the extent of damage around the fastener holes with fatigue loading.
