Abstract:To scrupulously predict the creep-fatigue life of materials, a creep life prediction model is firstly proposed in this study considering real-time creep damage derived from the Kachanov creep damage model; secondly, combined with the Chaboche fatigue damage model and the nonlinear coupling mechanism of continuous damage mechanics, a creep-fatigue life prediction model of material is ulteriorly presented in this paper; finally, the effectiveness of the creep-fatigue life model is corroborated by experiment data… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
