Flapwise bending vibration analysis of rotating multi-layered composite beams

A modeling method for the flapwise bending vibration analysis of a rotating multi-layered composite beam is presented in this paper. For the modeling method, the shear and the rotary inertia effects are considered based on Timoshenko beam theory and hybrid deformation variables are employed to derive the equations of motion. Dimensionless parameters are identified from the equations of motion and the combined effects of the dimensionless parameters on the modal characteristics of the rotating composite beams are investigated through numerical study.
