     modeling the buckling of multi walled carbon nanotube (mwcnt) probes/actuators in the vicinity of thin and thick graphite has been carried out for the first time via two analytical approximation methods as well as a numerical one. a hybrid nano-scale continuum model based on lennard-jones potential is applied to simulate the intermolecular force-induced deflection of mwcnt. the critical values of mwcnt tip deflection and mwcnt-graphite attraction at the onset of the instability are computed. in addition, minimum nanotube-graphite initial gap and stable length of freestanding cnt are determined as basic parameters for engineering applications and nano-devices design. the stable length of mwcnt is determined as a function of its geometrical and material characteristics, initial gap and number of graphene layers.
