Multiscale fatigue life prediction model for heterogeneous materials

A multiscale fatigue life prediction model is developed for heterogeneous materials. The proposed model combines a two-scale asymptotic homogenization approach in time with a block cycle jump technique into a unified temporal multiscale framework that can be effectively utilized for arbitrary material architectures and constitutive equations of microphases. The unified temporal multiscale approach in combination with a spatial multiscale approach based on the reduced order homogenization is characterized for high temperature ceramic matrix composites.
