Research Abstract

To predict the fatigue strength of a bolt, and to prevent the failure, it is necessary to know the residual stress induced by thread rolling process precisely. In this study, the X-ray measurement and computer simulation were performed for large-scale thread root model made by rolling. By comparing the results, the model has been proposed to calculate the residual stress distribution. The results from fatigue test show that the fatigue strength of a bolt can be predicted from the local stress distribution obtained by computer analysis using the hypothesis presented.
