 abstract = {We use classical molecular dynamics simulations to study the collapse of
single (SWNT) and double-walled (DWNT) carbon nanotube bundles under
hydrostatic pressure. The collapse pressure (p(c)) varies as 1/R-3,
where R is the SWNT radius or the DWNT effective radius. The bundles
show similar to 30% hysteresis and the hexagonally close packed lattice
is completely restored on decompression. The p(c) of DWNT is found to be
close to the sum of its values for the inner and the outer tubes
considered separately as SWNT, demonstrating that the inner tube
supports the outer tube and that the effective bending stiffness of
DWNT, D-DWNT similar to 2D(SWNT). We use an elastica formulation to
derive the scaling and the collapse behavior of DWNT and multiwalled
carbon nanotubes.},
