摘要：

In the present study, vibration of rotating composite beams is studied. Different beam theories are used in the formulation including Euler-Bernoulli, Timoshenko and Reddy beam theories. Ritz method is used in the solution of the problem. Simple polynomials are chosen for the displacement field. The continuity of transverse stresses is satisfied among the layers. Results are obtained for different orthotropy ratios, rotation speed, hub ratio, length to thickness ratio of the rotating composite beam and different boundary conditions. (C) 2015 Elsevier Ltd.
