A new creep-fatigue crack growth model and a correlation of the creep-fatigue crack growth rate with unified constraint parameter
International Journal of Fatigue(2023)
Abstract
•A new creep-fatigue crack growth (CFCG) model was proposed and verified.•The unified constraint parameter, Ap, was extended to creep–fatigue loading.•The CFCG rate has a linearly correlation with the unified constraint parameter, Ap.
