Abstract

Shape effect on partial slip behavior and load partition behavior in the friction-type butt joint is computed by using nonlinear discrete models. In the past studies, partial slip behavior of the friction-type joint, as compared with the bearing-type one, is regarded as insignificant because it exerts no significant effect on the major slip load. For the establishment of a more reasonable, economical and synthetic joint design, however, it is necessary to investigate these behaviors. In addition to this study, the relationship between fatigue stress and partial slip stress is investigated. The result shows the possibility that the defacement of the frictional surface at the edge bolt has one of the important effects upon the fatigue strength, as well as the stress concentration behavior. According to this assumption, an attempt has been made for prediction of the relative fatigue strength of the joints from partial slip stress of the edge bolt.
