In this paper, the free vibration of a functionally graded (FG) rotating beam based on Timoshenko beam theory has been
analyzed. The FG rotating beam assumed to be graded across the thickness and the material properties of the FG beam
assumed to vary continuously through the thickness of the beam according to a power law distribution of the volume
fraction of the constituent materials. Governing equations are solved using differential transform method. To verify the
present analysis, the results of this study are compared with the available results from the existing literature. The effect
of beam parameters such as constituent volume fractions, slenderness ratios, hub rotation speed and hub radius on the
natural frequencies and mode shapes of the rotating beam is comprehensively investigated. The functionally graded
composite material plays a significant role in vibration characteristics of the rotating FGM thick beams.
