We present effective and simplified methodology to simulate and investigate mechanical properties of vertically aligned multiwall carbon nanotubes (MWCNTs). Unlike conventional solutions, we considered nanotube as a beam with a fixed end and a free end, allowing us to employ the mechanics of beam used as cantilever. Considering the atomic force microscopy (AFM) force-distance measurement as possibility to experimental determination of CNTs mechanical properties, we simulated the interaction of carbon nanotube structure with AFM cantilever at the applied force. We investigated the effect of inner and outer radius, different values of Young’s modulus, and various lengths of MWCNTs. The presented methodology is a significantly quick simulation approach providing validated information about MWCNTs mechanical behavior.Keywords: Multiwall carbon nanotubes, mechanical properties, Young’s modulus, beam, AFM
