Abstract

This paper employs atomic-scale finite element method (AFEM) to study buckling and post-buckling behavior of single-walled carbon nanotube (SWNT). The achieved curve of average strain energy per atom via strain and critical strain for (8, 0) SWNT agree well with the recent molecular dynamics (MD) simulations. In the strain energy curve for (7, 7) SWNT, there are obvious jumps when the morphology changes abruptly, and in the stages of post-buckling, the strain energy changes approximately linearly with strain. The morphology at each characteristic strain can also be obtained in detail. Compared with MD simulations, AFEM only uses much less computing time, thus it is a very efficient way to study buckling and postbuckling of SWNT.
