Abstract

The purpose of this study is to establish the fatigue design criteria for the notched structural components subjected to high mean stress. In order to do it, the effects of stress concentration factor on the monotonic and cyclic tensile properties were investigated. Based on the results, two fatigue design approaches for the notched specimen using Goodman diagram was established and verified by comparing with the experimental result.
