Abstract

In transverse fatigue of a bolted joint, althogh the real fatigue limit (the highest nominal stress at the root of the first thread of bolt without generating fatigue failure) is the same for bolts with the same size and property class, the apparent fatigue limits (the highest amplitude of transverse vibration force which can be applied to the bolted joint without generating fatigue failure) vary according to the bolt tightening conditions. Hence, it is necessary to develop a guideline for safety and design of bolted joints under transverse vibration. In this study, the relationship between the apparent fatigue limit and the real fatigue limit has been experimentally revealed. The method to predict the apparent fatigue limit using the real fatigue limit has been developed.
