Axial stability of externally pressurized carbon nanopeapods

In this paper, the axial stability of externally pressurized carbon nanopeapods, i.e. carbon nanotubes doped with fullerene molecules, is investigated using a continuum-based elastic shell modelling. The modelling takes into account the non-bonded van der Waals interactions between the nested fullerenes and the host nanotube. According to the developed modelling, it is generally concluded that the axial stability of the carbon nanopeapod is less than that of a carbon nanotube under otherwise identical geometric and physical conditions
