The torsional mechanical properties of hollow Cu nanowires supported by carbon nanotubes (CNTs) are studied by all atoms molecular dynamic simulation. It is found that the critical angles of Cu nanowires almost do not decrease when the temperature increases to a limit value, and this invariant feature also has been found as the torsional loading rate is lower than 4.5×1012°s−1. Due to the support...
The paper considers the initial (from nanometers) scales of multiscale solid structures using well-known carbon nanotubes (hollow nanorods) and nanowhiskers (solid nanorods) as an example. It is shown that structural anisotropy contributes significantly to the mechanical properties of nanotubes and nanowhiskers. It is demonstrated that the rod systems, beginning with those of nanometer cross-sections,...
