Computational multiscale analysis and optimization of multiphase hierarchical structures within a continuum micromechanics framework
Hierarchical multiphase systems such as plant structures apply the concept of microheterogeneity repetitively across a hierarchy of well-separated length scales: composite microstructures at a smaller scale form the base materials for new microstructures at the next larger scale. Their complex …
