The elastic behavior of radially functionally graded (RFG) transversely isotropic materials is crucial for the reliable design of advanced cylindrical structures used in aerospace, biomedical, and energy applications. Accurate three-dimensional prediction of stress and deformation fields is required, as material anisotropy and radial gradation strongly affect structural integrity and performance. Existing analytical models often rely on simplifying assumptions that limit their ability to capture both global and localized elastic responses. This study presents an analytical investigation of the three-dimensional elastic response of cylinders composed of RFG transversely isotropic materials. A stress-free lateral surface and equilibrium boundary conditions at the cylinder ends are considered. The governing elasticity equations are solved using an asymptotic integration method, enabling a clear decomposition of the solution into penetrating, boundary effect, and boundary layer components. Penetrating solutions control the global response, while boundary effect solutions represent localized end phenomena consistent with classical shell behavior. The proposed formulation extends existing analytical frameworks by providing a unified and physically interpretable description of global and local elastic responses in radially graded anisotropic cylinders, offering a robust theoretical basis for the accurate analysis and optimal design of advanced composite cylindrical structures.
