The stress averaging approach is expected to account for effects that influence the support around notches via the micro-structural support length ρ*. This study thus investigates the applicability of the stress averaging approach for welded joints in engineering structures exposed to sub-zero temperatures. For this purpose, fatigue test results of welded joints in the temperature range of 20°C down to −50°C are assessed. It is shown that it is possible to assess data for different temperature with the same reference fatigue curve while maintaining a small scatter without the need for modification factors.en1744-53022021S1216224Fatigue assessment methodsFinite element analysisnotch sensitivitysub-zero temperatureswelded jointsJournal Article10.1080/17445302.2021.1906194Journal Article
