Hierarchical lattice: Design strategy and topology characterization

The structure-material integrated design is an art-of-state concept and be enabled by additive manufacturing. lattice material classified into structure as well because mechanical properties are determined its topology. However, the lack of a flexible strategy hinders achieve candidate. This work suggests strut-nested based strategies to effectively conduct hierarchical design. strut in larger-scale can replaced smaller-scale through rotation, stretching, translation operations combining local global numbering, thereby complete multi-scale skills elucidated with custom-developed algorithm; serious complex lattices influence structures on significant parameter, length-to-diameter, identified.
