Size optimization of micro-frame structures for designing multiscale structures
Nihon Kikai Gakkai ronbunshu, 2022 In this paper, we propose a multi-scale optimal design method for determining the member diameters of minute micro-frame structures in a macro-structure. The microstructures and the macrostructure are bridged by the homogenization method.
