Özet
In this study, the stability behavior of multilayer cylindrical shells made of functionally graded nanocomposite
layers (FG-NCLs) subjected to the lateral pressure in thermal environments is investigated. It is postulated that
nanocomposite layers forming layered cylindrical shells are made of single-walled carbon nanotube (SWCNT)-
reinforced polymers that have four types of profiles based on the uniform and linear distributions of mechanical
properties. The material properties of SWCNTs are assumed to be dependent on location as well as temperature
and are obtained from molecular dynamics simulations. The governing equations are derived as partial differ ential equations within shear deformation theory (SDT) and solved in a closed form, using the Galerkin pro cedure, to determine the lateral critical pressure (LCP) in thermal environments. The numerical representations
relate to the buckling behavior of multilayer cylindrical shells made of functionally graded nanocomposite layers
under the uniform lateral pressure for different CNT patterns and temperatures within SDT and Kirchhoff-Love
theory (KLT).
