Multiscale modelling strategy for predicting fatigue lives and limits of steels based on a generalised evaluation method of grain boundaries effects
Source abstract
Abstract
Multiscale modelling strategy for predicting fatigue lives and limits of steels is proposed based on a generalised method for evaluating grain boundaries’ (GBs) effects on fatigue crack growth. The proposed strategy is a modification of our previous works that extends the applicability from only low-grade ferrite steels to high-grade bainite steels. A microstructure model was developed considering distances between GBs and misorientations between adjacent grains. The strategy was validated by comparison with experiments using two ferrite-pearlite and one bainite steels; results indicate the strategy predicted fatigue lives and limits of steels with microstructures from coarse ferrite to fine bainite grains.
