Abstract

The effect of stress hold time t//H and stress rise time t//R on corrosion fatigue crack growth rate is studied in the range from f equals 6. 1 multiplied by 10** minus **1 Hz to 4. 63 multiplied by 10** minus **3 Hz. In high frequency region, crack growth rate is almost cycle dependent against frequency as affected by t//H. As t//H increases, time effect becomes more and more remarkable. On the other hand, under corrosion fatigue for t//H equals 0, crack growth rate is both time and cycle dependent in wider range of frequency, da/dN is formulated as a function of t//R and t//H.
