||Vertically aligned carbon nanotubes, Stress-strain, Finite element modeling,
||The super-long, vertically aligned carbon nanotubes (SL-VACNTs)
are novel carbon nanomaterial produced from template-free synthesis. The mechanical
responses of such material have been investigated by continuum finite
element modeling and compared with experimental observations. The crushable
foam model has been adequate in modeling the stress-strain curve and deformation
of the SL-VACNTs under compression. SL-VACNTs are seen to exhibit transient
elastic deformation at small displacement and then plastic deformation at large displacement.
The deformation mostly occur at the position immediately beneath the
compression platen (indenter face) due to the high stress/strain concentrations.
