THERMAL BUCKLING ANALYSIS OF EMBEDDED SINGLE-WALLED CARBON NANOTUBES WITH ARBITRARY BOUNDARY CONDITIONS USING THE NONLOCALTIMOSHENKO BEAM THEORY

摘要

In this paper, the thermal buckling behavior of single-walled carbon nanotubes (SWCNTs) embedded in an clastic medium is studied. To this end, the SWCNTs are modeled based on the nonlocal Timoshenko beam theory into which the effect of the elastic medium is incorporated The generalized differential quadrature (GDQ) method is employed to discretize the governing differential equations and to consider different commonly used boundary conditions (BCs). For simply supported BCs, the results obtained from the present analysis are compared with the ones from the exact solution and an excellent agreement has been achieved. The effects of the aspect ratio, nonlocal parameter and the Winkler parameter on the dimension/ess critical buckling temperature are carefully investigated.
