AB - <p style="text-align: justify;">Variational principles are derived in order to facilitate the investigation of
the vibrations and stability of single and double-walled carbon nanotubes conveying a
fluid, from a linear time-dependent partial differential equation governing their displacements.
The nonlocal elastic theory of Euler-Bernoulli beams takes small-scale effects
into account. Hamilton’s principle is obtained for double-walled nano-tubes conveying
a fluid. The natural and geometric boundary conditions identified are seen to be coupled
and time-dependent due to nonlocal effects.</p>
