Investigation on Buckling Behavior of Short MWCNT

This paper aims to investigate the buckling behavior of short multi-walled carbon nanotubes (MWCNTs) under compression using molecular dynamics simulations. The effect of the number of walls and length of MWCNT on the buckling behaviors is investigated. The results show that the buckling behaviors of short MWCNTs are different from single wall carbon nanotubes (SWCNTs) and slender MWCNTs. Interestingly, the buckling strain of short MWCNTs has a downward trend with the number of walls increasing. In addition, the length of MWCNT has also significant effect on the buckling strain. These benchmark data may be used to examine the applicability of continuum mechanics models in predicting the buckling behavior of short MWCNTs.
