Static friction limit;
In this study, the aim is to deduce the static friction limit of contact interfaces in bolt friction joints by analyzing other bolt friction joints with the same contact surface but in a different shape. By using the Weibull mathematical distribution to deal with microelements on the contact surface, the friction limit of a certain type of bolt connection was statistically predicted from other types of bolt connections with the same contact surface. As a result, this research succeeded to predict the friction limit of bolt joints with different numbers of contact surfaces and with different numbers of bolt rows. Another result of this research both the stress ratio and the Weibull stress ratio showed a high prediction accuracy.
