ANALYSIS OF A SIMPLIFIED METHOD FOR DETERMINING FATIGUE CHARTS ΔS-N ON THE EXAMPLE OF WELDED AND SOLDERED CONNECTORS

摘要

The paper describes the method of determining fatigue charts Delta S-N, which is particularly useful in the description of fatigue properties of welded and soldered joints. This method is based on IIW (International Institute of Welding) guidelines and FITNET procedures. This method makes it possible to design Delta S-N charts in a probabilistic approach, which is important in the reliability analysis of structural elements. The work also contains examples of charts resulting from the development of test results for selected welded and soldered joints.
