The original primary objective of this study is to conduct a comprehensive investigation into the free vibration behavior beams with porosity, reinforced by carbon nanotubes (CNTs). These are supported an arbitrary orthotropic variable elastic foundation (AOVEF). focus lies on understanding how presence porosity and CNT reinforcement, coupled complex support provided AOVEF, influences characteristics beams. In addition, we intend examine impact number micromechanical models properties these Four nanotube variables introduced symbolize several variations. CNTs' mechanical examined through variety models. Shear deformation effects considered account in framework higher-order shear (HSDT) beam theory. equations motion constructed using Hamilton's concept equation system for FG-CNT ends solved via Navier methodology. A new approach modeling Arbitrarily Orthotropic Variable Elastic (AOP-VE) foundation. It builds Winkler layer but introduces idea response along length Unlike Winkler-Pasternak model, AOP-VE allows control over directional Pasternak looks multiple aspects, involving various distribution kinds CNTs, factors, mode values, side-to-length ratio, angle variation. results indicate that parameters have major effect inherent features novel findings improve subject topic set standard future studies.
