The objective of this study is to investigate parametrically the natural frequencies of the moderately thick, sandwich, circular beams. The element matrix is based on the Timoshenko beam theory including the rotary inertia in the formulation. The curved element involves two nodes and each node has three translations, three rotations, two shear forces, one axial force, two bending moment and one torque (12DOF). A parametric study is performed on the natural frequencies of sandwich beams with various thin facesheets. The results are verified with the available commercial CAD programs.
