The earliest atomistic simulations of CNT mechanics predicted unusually large Young’s modulus (of up to 5 Terra Pascal [TPa] or five times larger than the modulus of diamond) and elastic limits (of up to 20 to 30% strain before failure) [33]. These © 2005 by CRC Press LLC Computational Nanotechnology of Carbon Nanotubes 33 predictions immediately raised the intriguing possibility of applying the nanotubes as super-strong reinforcing fibers with few orders of magnitude higher strength and stiffness than any other known material.

Coupled with the electronic-structure solution of the many-atoms system is also the possibility of simulating the dynamic evolution as a function of time. Several accurate quantum molecular dynamics schemes have been developed, in which the forces among atoms are computed at each time step via quantum mechanical calculations within the Born-Oppenheimer approximation. The dynamic motion for ionic positions is still governed by the Newtonian or Hamiltonian mechanics, and described by molecular dynamics.
