dc.description.abstract | The movement of a 5 vertical bar 7 defect in the plastic deformations of a carbon nanotube (CNT) plays the role of dislocation glide in the plastic deformations of metals. This work is concerned with the atomic shift mechanism of the 5 vertical bar 7 defect and the energy barrier when the CNT is subjected to tensile loading. Action-derived molecular dynamics (ADMD) is applied to find the minimum energy path and the energy barrier. It is found that the tensile loads make it easy for the 5 vertical bar 7 defect to glide, and lower the energy barrier. The minimum load level that makes a 5 vertical bar 7 defect glide freely with no energy barrier in the presence of an adatom is obtained. | - |
