Morphological changes for (10, 10) single-walled carbon nanotube . (a) Before the onset of buckling. (b) At , buckling occurs with two identical flattenings perpendicular to each other. (c) At , the upper flattening pushes into the lower one while maintaining a straight cylinder axis. (d) Further reduction in length at causes the tube to buckle sideway with bond breaking and reformation at the location of collapse.
