To ensure the structuresafety, a lot of special bolts and nuts were studied previously. In this paper, a slight pitch difference isconsidered between the bolt and nut. Here, the pitch of the nut is αμm larger than the pitch of the bolt. The fatigue experiment is performed for three kinds of specimens with different levels of pitch difference. The obtained S-N curves show that the fatigue life is extended by about 1.5 times by introducing the suitablepitch difference especially under the high stress amplitude. According to the detail investigation on thefractured specimens, it is found that the fractured positions and the crack configuration are totally different by introducing the pitch difference. To find out the mechanism of the improvement of the fatigue strength, the finite element method is also applied to calculate the stress amplitude and mean stress at each bottom of bolt threads.","subitem_description_type":"Abstract"}]},"item_23_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"3rd International Symposium on Fracture Fatigue and
