This is not universally applied in aerospace. My last "big" company took no consideration for clamp friction in shear joints. Each fastener was analyzed as an individual pin joint....Bolts and rivets mostly work by establishing clamp loads between the joined members. The joint has security only as long as the friction is larger than the active loads and the tensile loads do not open the joint. If active loads exceed friction or the joint opens and closes, the joint works and fatigue develops in the joined members and in the fastener. In the end, we need joints to be clamped securely against motion...
