Flapwise bending vibration analysis of functionally graded rotating beams with concentrated mass.

The article presents a study that analyzes the flapwise bending vibration of functionally graded rotating concentrated mass. Discussion on the method of the study that examines the material properties of the mass through Rayleigh-Ritz method and dirac delta function is provided. The influence of the morphology, hub radius ratio, and angular speed of the flapwise bending natural frequencies of functionally graded beam is also investigated.
