English abstract In this paper, the thermal buckling characteristics of armchair single-walled carbon nanotube (SWCNT) embedded in a one-parameter elastic medium are investigated using a new nonlocal first-order shear deformation theory (NNFSDT). The present model is able to consider the smallscale effect as well as the transverse shear deformation effects of nanotubes. The equivalent Young’s modulus and shear modulus for armchair SWCNT are obtained by employing the energy-equivalent model. A closed-form solution for nondimensional critical buckling temperature is obtained in this investigation. The results illustrated in this work can provide a significant guidance for the investigation and design of the novel generation of nanodevices that make use of the thermal buckling characteristics of embedded SWCNT
