This paper reviews quantitively the multiaxial fatigue assessment of steel and aluminum welded joints, focusing on Eurocodes (ECs) and the recommendations of the International Institute of Welding (IIW). Extensive fatigue data under constant and variable amplitude loading are reanalyzed using stress analysis approaches such as nominal stress, hot spot stress, and effective notch stress. Evaluation of the ECs and IIW criteria reveals an effective assessment of multiaxial fatigue, with a satisfactory level of conservatism. Further research is needed especially for variable amplitude (VA) loading to enhance the precision and reliability of assessments, contributing to improved design practices and structural integrity in welded joint applications. Highlights: The multiaxial fatigue criteria proposed by EC3 and the IIW are reviewedDesign criteria are applied in terms of nominal, hot spot, and effective notch stressBoth constant and variable amplitude load histories are consideredStandard approaches are characterized by a large level of conservatism [ABSTRACT FROM AUTHOR] |
