Very thick high strength steel plates (i.e. ) are being used for the construction of wind turbines nowadays. The fatigue behaviour of such thick plates is completely different than conventional thin sheets. This is due to the significant plane strain effects, the through thickness heterogeneous microstructures, the different through thickness mechanical behaviour, and the presence of defects. To the best knowledge of the authors, there is a lack of knowledge on the fatigue behaviour of such thick plates. This paper presents an experimental campaign on the fatigue behaviour of thermo-mechanically rolled S460 high strength steel with thickness of 100 mm. The fatigue tests are conducted on small and large scale specimens to characterise the size effects on the fatigue behaviour. Microstructural analysis is conducted to characterise the microstructures and presence of defects. Through thickness Vickers hardness measurements are conducted. The fatigue experimental results are compared Murakami approach.
