Young's modulus of single-walled carbon nanotubes

We report in detail that unlike other materials, carbon nanotubes are so small that changes in structure can affect the Young's modulus. The variation in modulus is attributed to differences in torsional strain, which is the dominant component of the total strain energy. Torsional strain, and correspondingly Young's modulus, increases significantly with decreasing tube diameter and increases slightly with decreasing tube helicity.  Journal of Applied Physics 84, 1939 (1998).


Tienchong Chang's picture

It is really a classic paper. I cited it in our JMPS (51, 1059, 2003) paper, but missed it in the successive related works since most of my documents was lost after one of my hard disk broken. I think we should acknowledge your contributions on this topic in the future works. 

thanks for Dr. Chang's nice comment, and thanks for iMechanica in providing such a wonderful platform to share our research so effectively.
