چکیده مقاله

Nonlinear dynamic stability of double-walled boron nitride nanotube (DWBNNT) under combined electro-thermo-mechanical loading is considered in this paper. DWBNNT is modelled by Timoshenko beam model that considers the effect of rotation inertia and shear loading. Internal fluid passes through the DWBNNT. To calculate the interaction of fluid and DWBNNT, Navier-Stokes relation is used considering bulk viscosity and slip boundary condition. Coupling between electrical and mechanical fields is considered using charge equation. DWBNNT is embedded in visco-Pasternak foundation and the effects of Van der Waals forces, small scale parameter and surface energy are considered also.
