In many cases continuum mechanics has proved to be an appropriate method for
investigating the mechanical behavior of carbon nanostructures reducing the
computational requirements compared to atomistic methods significantly.
The main modeling issues arising in continuum mechanics modeling of multi-layer
carbon nanostructures are briefly discussed.
These issues involve the
continuum modeling of (i) the atomic layers, (ii) the covalent interlayer
bonds, (iii) the van der Waals interactions, and (iv) the excess surface energy
due to curvature.
Continuum mechanics methods in conjunction with the finite element method are
applied to investigate the compressive behavior of carbon crystallites and a
possible growth limit of carbon onions.
