Non-Symmetrical Load Influence on Aluminum Alloy-Welded Joint Fatigue Limit
The mean stress caused by a non-symmetrical load significantly influences the fatigue limit. The fatigue limit of an aluminum alloy-welded joint is analyzed in the present paper using a stress ratio of 0.3. Our results show that the aluminum alloy-welded joint fatigue limit amplitude can be accurately converted from the mean stress using the Goodman beeline and Eurocode9 methods.
