...Sayed A. Nassar; Mohan Ganganala A nonlinear model is proposed for studying the effect of the eccentricity of applied tensile forces on the clamp load loss in bolted joints that were initially tightened beyond the bolt elastic limit while the joint remained in the elastic range. A closed form...

... bolted joints threaded fasteners bearing friction torque-tension relationship thread friction torque pitch self-loosening The safety, the reliability, and the quality of bolted connections are significantly affected by both the level and the stability of the fastener tension, which is most...

...Massimiliano Pau; Antonio Baldi Bolted joints are a widespread type of connection used in mechanical engineering, but their performance, in terms of contact area size and shape and pressure distribution, is not easy to verify due to the nature of closed contact, which makes it difficult...

... of the external excitation on the loosening of a single-bolt joint. The rate of drop in the joint clamp load (fastener tension) per cycle, as well as the total number of cycles that would cause the complete loss of clamp load, are monitored. In the mathematical model, the differential equations of linear...
