Original Abstract

This contribution addresses the fatigue life prediction of thin-walled welded joints, which play indispensable roles in various aircraft structures. Following the recommendations of the International Institute of Welding (IIW), three main fatigue life prediction approaches (nominal stress, structural stress, and notch stress based predictions) are described. A comparative study is conducted on six types of specimens, providing insights from their fatigue testing and numerical determination of each stress type. The S-N curve slopes obtained from the evaluated data are consistent with general assumptions regarding thin-walled welded structures and a considerable split, dividing the evaluated data into two separate S-N curves, suggests the need for additional corrections to achieve more accurate fatigue life predictions.
