The purpose of the present study was to develop a multi-scale optimization which optimize topology of microstructure and/or kind of material of composites.In this achievement we developed successfully the new method, namely "multi-scale topology optimization". This method is based on the finite element method and significant approach from a view point of material design. In addition to above achievement, we also developed the new approach considering elastoplastic material model for composites and so-called phase-field method.These results were presented in six academic journals. So far, the four papers were published and the other two papers are under review process. Furthermore the results of the present study will be presented in the national and international congress totally 13 places.
