Abstract:
We calculate and analyze the torsional mechanical behavior of single-walled and double-walled carbon nanotubes using classical molecular dynamics． It is found that the torsional stiffness is nearly independent of their structures for double-walled carbon nanotubes( DWCNTs) with same diameter and length． However， if outer tube of the DWCNT is zigzag-type， its axial stress will extend the DWCNT，whereas other type of outer tube will shrink the DWCNT． These results are very important for designing of the nano-electro-mechanical systems( NEMS) ．
