| Outline of Final Research Achievements |
Buckling analysis was performed on multi-walled CNTs using molecular dynamics methods. By evaluating the atomic elastic stiffness coefficient, it was revealed that local buckling, in which the cylindrical shape partially collapses, occurs at the point where the deformation resistance against the shear strain direction in the out-of-plane direction is completely lost.
In addition, the influence of the interaction with the periphery on the buckling behavior of multi-walled CNTs was also clarified by examining buckling analysis on models in which C60 was encapsulated inside the CNT and composite models in which the outside was filled with a polymer structure.
