Outline of Final Research Achievements

Ductility is the most important mechanical characteristic for metallic materials and has co-relation with the strength and deformability. Those performances are determined by the microstructure, namely crystalline structure. In the meanwhile, it is well known that topology optimization is a powerful design tool to maximize the mechanical performance of structures/materials by applying computers. The present study developed a material design method to maximize the mechanical performance of polycrystalline microstructure, such as stiffness, ductility and thermal conductivity, and verified its usefulness by a series of numerical examples.

Academic Significance and Societal Importance of the Research Achievements

金属材料をはじめとする結晶材料は社会インフラを構成する基盤材料であり,その性能を改善するためにこれまで多くの研究が行われている.しかし,従来の方法はこれまでの実績と経験則に依存する部分が多く,より高度な材料の開発を推進するには限界がある.本研究は,それを改善するためのものであり,今後の先端材料開発における上流側の設計に大きく寄与するものであると考える.
