Abstract
The monoscale consideration will not be applicable to multiscale materials, which motivates the formulation of multiscale fatigue model for metal materials. Scale segmentation involves multiple ranges. Strain energy density (SED) criterion could be a possible way to the solu- tion of multiscale fatigue and fracture. Base on SED criterion, a multiscale fatigue crack growth model is formulated. Results show the multiscale model is able to offer reasonable explanation for fatigue test.File in questo prodotto:
