Fatigue cracks in Eurofer 97 steel: Part II. Comparison of small and long fatigue crack growth
Original language description
The fatigue crack growth rate in the Eurofer 97 steel at room temperature was measured by two different methodologies. Small crack growth data were obtained using cylindrical specimens with a shallow notch and no artificial crack starters. The growth ofsemicircular cracks of length between 10?2000 lm was followed in symmetrical cycling with constant strain amplitude (Re = 1). Long crack data were measured using standard CT specimen and ASTM methodology, i.e. R = 0.1. The growth of cracks having the length in the range of 10?30 mm was measured. It is shown that the crack growth rates of both types of cracks are in a very good agreement if J-integral representation is used and usual assumptions of the crack closure effects are taken into account.
