چکیده مقاله
In this article, buckling of two double walled boron nitride nanotubes (BDWBNNT) under
combined loadings of electro-thermo-mechanic has been investigated as Fig. 1. The two
BDWBNNTs are assumed to be bonded by an enclosing elastic medium. DWBNNTS have been
simulated by Timoshenko beam model [1] where the piezoelectricity is inherent properties of
Boron-Nitride nanotube. Nonlocal elasticity [2-3], Pasternak modulus parameter [4], the effects
of temperature change, van der Waals forces between the inner and outer nanotubes and
aspect ratio are utilized for modeling the BDWBNNTs. It is assumed that the displacement of
BDWBNNT is in the one plane for in-phase buckling state that the nanotube are buckled in the
same direction (synchronous) and in out-of-phase sequence of buckling the nanotube is buckled
in opposite direction (asynchronous). The small-scale parameter has influence on the instability
(or buckling) of BDWBNNTs.
