چکیده:

In this work, control of postbuckled configuration of double-walled conveying fluid carbon nanotubes is investigated. The nonlinear governing equations of motion and boundary conditions are derived based on Eringen nonlocal elasticity theory and Timoshenko beam model. Von-Karman strain-displacement is used to model the geometric nonlinearities. The Van der Waals interaction between adjacent layers is taken into account. An analytical approach is employed to determine the critical fluid flow velocities and postbuckling configuration. An external static distribution force used to reduce postbuckled deflection
