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.
