BUCKLING OF DEFECTIVE CARBON NANOTUBES UNDER AXIAL AND TRANSVERSE LOADS
2014
Elastic buckling of single walled carbon nanotubes (SWCNTs) with di-, triple- and pinhole vacancy defects under the transverse and axial compression loading is investigated based on molecular structural mechanics. In this research, the effects of length, radius, loading ratio, and the position of vacancy defect on the buckling behavior of armchair and zigzag single-walled carbon nanotubes are studied. It is found that the position of pinhole-vacancy has a significant effect on the percent of the reduction of the critical buckling force. It is also seen, that the effect of loading kind on the critical buckling forces loses its importance if the length of carbon nanotube (CNT) increases.
