Simple approximate formulas for postbuckling deflection of heavy elastic columns
Hiroyuki Shima
Columnar buckling is a ubiquitous phenomenon that occurs in both living things and man-made objects, regardless of the length scale ranging from macroscopic to nanometric structure…
Buckling of Carbon Nanotubes: A State of the Art Review
Hiroyuki Shima
The nonlinear mechanical response of carbon nanotubes, referred to as their "buckling" behavior, is a major topic in the nanotube research community. Buckling means a deformation p…
Core-tube morphology of multiwall carbon nanotubes
Motohiro Sato, Hiroyuki Shima, Kohtaroh Iiboshi
The present paper investigates the cross-sectional morphology of Multiwalled Carbon Nanotubes (MWNTs) restrained radially and circumferentially by an infinite surrounding elastic m…
Multiple radial corrugations in multiwalled carbon nanotubes under pressure
Hiroyuki Shima, Motohiro Sato
Radial elastic corrugation of multiwalled carbon nanotubes under hydrostatic pressure is demonstrated by using the continuum elastic theory. Various corrugation patterns are observ…
Interacting quantum rotors in oxygen-doped germanium
Hiroyuki Shima, Tsuneyoshi Nakayama
We investigate the interaction effect between oxygen impurities in crystalline germanium on the basis of a quantum rotor model. The dipolar interaction of nearby oxygen impurities…
