On buckling of carbon nanotubes
Lublin University of Technology (LUT), Nadbystrzycka 38, Lublin 20-618, Poland
We investigated single walled Carbon Nanotube under an axially directed compressive line loading applied at both of its edges. The expected buckling behavior was studied by means of a molecular computation approach [1-2]. We formulated a global potential and searched for its minimum to obtain the equilibrium configuration. Beside the main parameter, viz. the value of the load, we were looking for a second parameter - the diameter of the tube. We were able to define the critical value of the diameter, for which the coincident case of local shell buckling was determined.
