چکیده
|
In this article, curvature effects on elastic thermal buckling of double-walled carbon nanotubes under axially compressed force are investigated using cylindrical shell model. also, the small scale effect is taken into account in the formulation. the dependence of the interlayer van der waals (vdw) pressure on the change of the curvatures of the inner and outer tubes at that point is considered. the effects of the surrounding elastic medium, curvature and the vdw forces between the inner and outer tubes increase the critical buckling load under thermal and axial compression loads, while small scale effect decreases it.
