Continuum damage mechanics based probabilistic fatigue life prediction for metallic material

open access: yesJournal of Materials Research and Technology, 2022
Based on continuum damage mechanics, a probabilistic method of predicting high-cycle fatigue life for metallic material is proposed. First, macro-meso two-scale stress–strain equations are established by combining Eshelby-Kroner localization law and ...
