dc.description.abstractThe growing needs and development of components for industry such as power sector, aerospace, etc. challenge the researchers to implement new methods and concepts to improve functional requirements of structure for enhancing the material strength. Such implementation is especially required in the case of rotating beams that are subjected to critical vibrations under centrifugal forces, large pressure loadings, effect of corrosion, temperature etc. The present paper studies the vibration characteristics of functionally graded rotating Bernoulli-Euler beam, which is symmetric and the material properties vary continuously in thickness direction from core at mid-section to the outer surfaces according to a power law relation. The natural frequencies of these beams are obtained using differential transform method (DTM) formulation. The effect of parameters such as power law index, hub radius and rotational speed on the natural frequencies of functionally graded rotating beam are studied through numerical studies and then compared with results obtained by Rayleigh-Ritz method.en_US
