Welds at plate ends and corners - a literature review. Hot spot stress & effective notch stress compared with fatigue tests
report
Welds at plate ends and corners in geometrically stress concentrated areas often occur in welded steel bridges and other steel structures such as ships. Often occurring details are mouse holes and loaded attachments. These details create complex stress situations and consequently challenging fatigue assessments. These assessments can be done by different assessment methods, such as the hot spot stress methods Type “a” or “b” and effective notch stress method. Applications of these methods are frequently shown and compared in literature, but studies showing reliable comparisons with fatigue test results from different sources are scarce. In the framework of the “Vervanging & Renovatie” (V&R) project of Rijkswaterstaat, a project has started to select or develop a fatigue assessment method for these welds at plate ends.
