Çift eksenli basınç yükleri altında auxetic çekirdek katmanlı akıllı sandviç plakanın mekanik özelliklerinin incelenmesi

This study uses high-order sharing deformation theory to model auxetic core layer smart sandwich plates and examines their mechanical properties. The outer layers of the smart plate consist of electro-elastic BaTiO3 (Barium Titanate) and magnetostrictive CoFe2O4 (Cobalt Ferrite) materials. The auxetic core layer consists of a metallic material (Nickel) with varying auxetic cell parameters. Three fundamental parametric characteristics of the auxetic core cell are modeled: wall thickness parameter, length parameter, and inclination angle. The equations of motion are derived from Hamilton's principle and resolved using the Navier method. The findings of this study will facilitate the optimal design of smart electromechanical systems intended for operation in high-temperature environments.
