The talk presents a practical multiscale-multiphysics design system, which integrates reduced order multiphysics-multiscale analysis; capabilities for life prediction and durability of composite structural components. The design system has been successfully deployed in aerospace industry for fatigue life prediction and environmental degradation of high temperature CMC and PMC components as well as in automotive industry for crash prediction of composite cars. The talk includes theory, implementation and applications. The case is made for a widespread adoption of multiscale methods in practice. We show that it is feasible to reliable predict the behavior of large-scale heterogeneous structural systems well into post-failure regime by accounting for fine-scale material details at a computational cost comparable to the phenomenological modeling of heterogeneous materials.
