Based on an empirical J-integral equation proposed earlier, surface fatigue crack growth rates along crack length and depth directions including the J-integral were developed. Using these expressions, the crack growth lives of a SUS304 steel at 550�� under bending loads are predicted. The fatigue crack growth experiment was carried out in the same condition. The results showed that the predicted curves of crack length and crack depth vs number of cycles agree well with the experimental data. It proved that the method described were available.
