Fostering Collaboration in Fatigue Assessment: New Benchmarks and Open-Source Tools from FABER

FABER Conference 2026, Split, Hırvatistan, 5 - 06 Mayıs 2026, ss.355-365, (Özet Bildiri)

This presentation highlights two parallel initiatives designed to deliver practical, community-driven

outcomes for the FABER Action. The aim is to present tools and data that the wider fatigue

community can adopt, use and further develop. First, we present a newly compiled benchmarkready

dataset for assessing TIG-dressed welded joints. This work stems from a recent STSM and

integrates geometric parameters and fatigue test data from a comprehensive literature review with

preliminary finite element analyses. The dataset supports the calibration and validation of local

stress-based fatigue models, directly contributing to WG5.3’s objectives. Second, we introduce

an open-source, modular software framework for systematically benchmarking multiaxial fatigue

criteria. Developed within WG4.3, the framework features a plugin-like architecture for easy

implementation and comparison of critical-plane, invariant-based and energy-based models against

experimental data under both in-phase and out-of-phase loading. It centralises non-proportional

loading handling and automatically generates comparative plots and summary tables for direct use

in reports and publications. We encourage FABER members and the wider research community

to adopt these resources, contribute new data and models and collaborate on refining these tools

to advance standardised and reliable fatigue assessment practices.
