High-Frequency Response Of Double-Layer Varying Thickness FG Plates Considering Sliding Motions

In this article, the high-natural oscillation properties of double-layer varying thickness FG plates considering sliding motions are investigated. A description and development of the fundamental equations are achieved by using the well-established and straightforward first-order shear deformation plate theory (FSDT) in conjunction with the methode of finite element (FEM). This computational limitations and present assumption were substantiated by conducting a comparation between numerical results obtained in our research and the others in reputable journals. The influence of three boundary conditions is considered and evaluated to affect the high-order natural vibration frequency response of the structure. Moreover, the complex structural model that has been proposed holds significant potential for some fields such as: nuclear, aerospacing engineering, and military engineering.
