Abstract
Molecular dynamic simulations are performed to study the deformation behavior of nanocomposite structures formed by the insertion of a carbon nanowire (CNW) into a carbon nanotube (CNW@CNT) under tension. The simulation results indicate that insertion of the CNW into CNT makes the plastic elongation increase. A superplastic deformation behavior is observed and finally, CNW@CNT is drawn to be a very long elongated nanobridge. During the tensile deformation, pentagon–heptagon defects, octagonal defects, and higher-order rings are observed. A large hole caused by some defects accelerates the fracturing of the CNT.
