Finite-element modeling for static bending and free vibration analyses of double-layer non-uniform thickness FG plates taking into account sliding interactions

The present article explores static bending and natural oscillation characteristics of double-layer non-uniform thickness functionally graded (FG) plates that are equipped with shear connectors. The fundamental equations are comprehensively described and developed by the utilization of the finite-element method (FEM), in conjunction with the widely recognized and straightforward first-order shear deformation plate theory (FSDT). The current hypothesis and computational framework have been validated through a comparative analysis of the numerical findings from this study with those reported in other esteemed publications. Parametric research is undertaken to explore the impact of geometrical and physical features on the structural response of the FG plate, with particular emphasis on the variation in thickness and distribution of shear connectors. The numerical findings obtained from this study can serve as a valuable point of reference for further orientation endeavors in the same domain. Furthermore, the proposed complex structural model can be referred to as an important idea for application in the fields of aerospace, nuclear, and military technology.
