However, additionally, the corroded and irregular morphology of the surface affects the steel's load-bearing capacity and its impact on the strength and elongation behaviour of the steel is not yet fully understood. These effects on the local behaviour of steel structures under tensile loading were investigated with tensile tests on naturally corroded steel specimens and nonlinear finite element simulations including the corroded surface morphology with a uniform surface idealation. The models also include the deformed specimen shape. The developed approach led to highly accurate parametric finite element models predicting the ultimate tensile strength and longitudinal position of fracture. The results show that all included aspects are essential for accurate simulations, while solely the maximum available surface resolution was not as decisive.en1754-212X|||1744-53022025Taylor and Francis Ltd.https://creativecommons.org/licenses/by/4.0/Corrosion | finite element analysis | integrity of steel structures | numerical simulation | strength analysisTechnology::623: Military Engineering and Marine EngineeringJournal Articlehttps://doi.org/10.15480/882.1514310.1080/17445302.2025.249242910.15480/882.15143Journal Article
