Nonlocal effect on axially compressed buckling of triple-walled carbon nanotubes under temperature field

摘要: This paper studies the small scale effect on buckling behaviors of triple-walled carbon nanotubes (TWCNTs) with initial axial stress under temperature field. The TWCNTs are modeled as three elastic shells coupled together through vdW interaction between different layers. Buckling governing equations CNTs firstly formulated basis nonlocal theory and results change then achieved. show that critical load is dependent temperature, parameter wavenumber. Some conclusions drawn will arise gradually increases wavenumber, can influence ratio corresponding local load. Furthermore, or without effects considered, same obtained value at low room condition, while high condition decreases increases.
