Abstract
One of the significant issues in the nanotube research community is buckling behavior. In the present work, the buckling of single-walled nanotubes (SWNTs), double-walled nanotubes (DWNTs) and multi-walled nanotubes (MWNTs) under axial compression is investigated. Buckling analysis for nanotube composite structures is performed by using layer-wise theory based on the nonlocal constitutive relations of Eringen. The governing equations of SWNTs, DWNTs and MWNTs are developed. Then analytical solutions are obtained using the state-space method. The effects of nanotube length, diameter and nonlocal parameter on the buckling loads are studied. The numerical results indicate that the nonlocal parameter is important for the buckling analysis of nanotube composite structures.
