112 カーボンナノチューブの変形に関する基礎的研究(セッション3) 112 Fundamental Research on Deformation of a Carbon Nanotube
Deformation of a carbon nanotube is studied by an analytical method. A single-walled carbon nanotube is regarded as a beam with a hollow cylindrical cross section. Deformation is analyzed by the beam theory introducing the von Karman strains to describe large deformation. As an illustrative example, the tube subjected to an axial compressive load and simply-supported at both edges is treated assuming a carbon nanotube attached to a probe of an atomic force microscope. The solution of first mode deflection is obtained explicitly. Numerical examples are presented to show the relation between the axial load and the large deflection.
