Outline of Final Research Achievements

This study proposes the state-of-the-art high performance structural systems by combination of hard and soft materials in order to prevent stress concentlation and to realize high durability and resilience. To do this, we have investigated the structural properties of some new structural technologies, such as pipe-in-pipe systems with granular core materials, laminate structures, carbon nanotubes, and so on. Theoretical and analytical researches have been carried out thoroughout the latest numerical techniques and we have shown some noble structural performances.
