Structural model of multi walled carbon nanotube

In this paper a theory about multi walled carbon nanotubes and a suitable way for modeling them using finite element method is presented. A brief reference to FEM modeling of a single walled carbon nanotube is given, as an introduction to modeling of multi walled carbon nanotube, consisting of several layers of SWNT. Also, theory on connection interface between nanotube layers and its influence on loading results is given. Based on previous work [4], a SWNT finite element model is used to model a multi walled carbon nanotube (MWNT). A brief theory concerning MWNT is given, as well as a theory of modeling a connecting interface between layers, as a result of van der Waals interactions. Different loading conditions are used for example of multi walled carbon nanotubes under specific load. Results are compared with results given by the other authors.
