Abstract
This research utilized higher-order shear deformation theory to model and analyze the thermomechanical vibration buckling behavior of auxetic core layered smart sandwich plates. The surface layers of the smart plate consist of magneto strictive CoFe2O4 (Cobalt Ferrite) and electro elastic BaTiO3 (Barium Titanate) materials. The hexachiral auxetic core layer consists of the metal biomaterial Ti-6Al-4V, which includes various auxetic cell parameters. This study analyses the effects of Auxetic core layer parameters on the thermo-mechanical vibration buckling behavior of the smart sandwich plate, along with the influence of external electrical and magnetic potentials applied to the surface plates over a wide range. The findings demonstrate that the thermo-mechanical buckling behavior of the smart sandwich plate can be regulated by appropriately adjusting the Auxetic cell and applying external electric and magnetic potentials. The findings of this study will facilitate the design of smart electromechanical systems suitable for high-temperature environments.
