Fig. 1. Comparison of creep damages calculated by life fraction rule and ductility exhaustion concept in calculating damages for 316H stainless steel at 570?°C (linear interaction, /3 and ×3 denote ωc+ωf=1, 1/3 and 3, respectively): (a) creep-fatigue interaction diagram; (b) total damage vs stress dwell (adapted from Reference [7]).
