Sažetak
Most of the components of modern wind turbines are made of ductile cast iron. Ferritic nodular cast iron grade EN−GJS−400−18−LT, in which graphite spheroids or nodules in a ferritic matrix provide large ductility and fatigue strength, is commonly used. In the last decade numerous experimental studies have been presented showing influence of microstructure on the mechanical behaviour of the nodular cast iron. However, there are only limited experimental data available on fatigue crack growth behaviour of EN-GJS-400-18-LT (e.g. Mottitschka et al., 2010) and still the effect of the graphite morphology (size, shape and distribution) as well as microstructure phase (ferritic and pearlitic) on fatigue properties of this material is not well documented (Čanžar et al., 2011). This paper presents an experimental and numerical study of the low-cycle fatigue behaviour of nodular cast iron EN−GJS−400−18−LT depending on the material microstructure.
