An atomistic modeling technique and molecular structural mechanics are used by Li and Chou [62] to calculated fundamental natural frequency of SWCNTs. A free and forced vibrations of SWCNT have been assessed by Arghavan and Singh [63] using space frame elements with extensional, bending and torsional stiffness properties to modeling SWCNTs and compared their results with reported results by of Sakhaee pour [64] and Li and Chou [62], Their results were in close agreement with two other results, within three to five percent.

The direct use of these models for nanoreinforced composites is questionable due to the significant scale difference. The development of nanoscale continuum theories that integrate continuum mechanics theories with the nanoscale molecular structure has aroused a greater interest. These modeling techniques are referred to as nanoscale mechanics or molecular structural mechanics in the literature, and they link the interatomic potentials of atomic structure to the continuum level of materials [64]. 

Li and Chou [73, 74] have reported a multiscale modeling of the compressive behavior of carbon nanotube/polymer composites. The nanotube is modeled at the atomistic scale, and the matrix deformation is analyzed by the continuum finite element method. The nanotube and polymer matrix are assumed to be bonded by van der Waals interactions at the interface. The stress distributions at the nanotube/polymer interface under isostrain and isostress loading conditions have been examined. They have used beam elements for SWCNT using molecular structural mechanics, truss rod for vdW links and cubic elements for matrix. The rule of mixture was used as for comparison in this research. The buckling forces of nanotube/ polymer composites for different nanotube lengths and diameters are computed. The results indicate that continuous nanotubes can most effectively enhance the composite buckling resistance.
