| Abstract | The manuscript presents a novel model reduction approach for periodic heterogeneous media, which combines the multiple scale asymptotic (MSA) expansion method with the transformation ¯eld analysis (TFA) to reduce the computational cost of a direct homogenization approach without signi¯cantly compromising on solution accuracy. The evolution of failure in micro-phases and interfaces is modeled using eigendeformation. Adaptive model improvement strategy incorporating a hierarchical sequence of computational homogenization models is employed to control the accuracy of the model. We present the model formulation and computational details along with the veri¯cation (with respect to direct homogenization) and validation (with respect to physical experiments) studies. |
