We recently published a paper in International Journal of Solids and Structures titled "A rod model for three dimensional deformations of single walled carbon nanotubes".(paper attached)

There are several research papers dealing with continuum modeling of a nanotube using shell theory. Longer nanotubes, however, appear more as a one dimensional rod but there is almost no work towards modeling of a nanotube using rod theory. The objective of this paper is to model a nanotube using rod theory. It also highlights challenges and associated future research plans. Not to mention, a one dimensional rod model is advantageous both from theoretical and computational viewpoint.
