000001790 520__ $$2eng$$aThe fatigue crack growth rate in the Eurofer 97 steel was measured by two different methodologies. Small crack growth data were obtained using cylindrical specimens with a shallow notch. No artificial crack starters were used. The growth of semicircular cracks of length between 10 – 2000 μm were measured in symmetrical tension-compression cycling with constant strain amplitude (Rε = -1). Long crack data were measured using standard CT specimen and ASTM methodology in stress control with R = 0.1. The growth of fatigue cracks with length in the range of 10 – 30 mm was determined. It is shown that the crack growth rate of both types of cracks are in a very good agreement if J-integral representation is used and reasonable assumptions of the crack closure effects are taken into account.
