Thermal effects on the mechanical analysis of temperature-dependent FG-CNTRC annular plates

The present study deals with the vibration and buckling of functionally graded carbon-nanotubereinforced composite (FG-CNTRC) annular plates subjected to thermal loading. Thermo-mechanical characteristics of the materials are temperature-dependent (TD). Based on Mindlin's plate theory and using Hamilton's principle, the governing equations are derived. The generalized differential quadrature (GDQ) approach and periodic differential operators are employed to numerically solve the problem. The proposed approach is verified through different comparative studies. Additionally, to study the impacts of involved factors on the instability and vibration characteristics of CNT-reinforced composites annular plates, a wide range of results is presented. The results reveal that considering the TD material properties considerably affect the mechanical characteristics of thermally-induced CNT-reinforced composite plates.
