The influence of a decreasing rate of stress intensity factor with crack propagation, d K/ d a , on a stress intensity threshold level, δK th , below which fatigue crack propagation becomes insignificant is investigated. Specimens, 200 mm wide, 10 m

The closure phenomena of fatigue cracks were investigated with a 1 mm gage length extensometer over the range of stress ratio, R, from −1 to 0.8. Plate specimens with a center slot of HT80 steel and SUS304 stainless steel were fatigued under push-p
