Abstract
The residual stress and elastic modulus for the surface and core layers of metallic nanotubes (MNTs) are studied based on molecular dynamics simulations. The resultant small-scale effect is then demonstrated in a case study on the vibration of MNTs. In contrast to previous assumptions, it is found that the residual stresses at the inner and outer surfaces differ by several times and change sensitively with the geometric size of MNTs. In addition, the core layer stress ignored in most previous studies can also exert substantial influence on the structural response of MNTs. It is believed that these results can provide important guidance for the future study and potential applications of MNTs.
