  • Low cycle fatigue of welded joints with aging influence
    Zaletelj, Henrik ; Fajdiga, Gorazd ; Nagode, Marko
    The article is a continuation of welded joints research, which is intended to improve the fatigue life prediction of the exhaust system's welded parts. It is focused on the low cycle fatigue (LCF) ... range, where the influence of high loads on the material durability was analyzed. Sometimes the practice shows an unprofitable production of some intensively loaded parts evaluated in the range of high cycle fatigue or fatigue endurance limit. Numerous LCF tests of samples without weld, with weld and with aging influences were performed. Testing was performed on a servo hydraulic test machine where the strain was controlled. The tables and graphs show the results of the monotonic tension tests, LCF tests and the results of the artificial aging influences on the welded joints. The article also includes the fatigue degradation regarding the weld influence and minor aging effect on fatigue properties at higher strains. The results present a contribution to the progression of knowledge and the research of new technologies, especially in the area of the fatigue of welded parts under high loads.
