A hypothetical engineering alloy is subjected to high temperature fatigue crack growth at a cyclic frequency of 5 Hz. The transition time from small scale creep to extensive creep, Eq. 16.21, under those testing conditions is 50 s. Comment on the validity of different fracture mechanics parameters to characterize the creep-fatigue fracture of the alloy.
