Numerical and Experimental Study of Friction Damping Blade Attachments of Rotating Bladed Disks
International Journal of Rotating Machinery, 2006 In order to mitigate high cycle fatigue risks in bladed disks, the prediction of the vibration levels early in the design process is important. Therefore, the different sources of damping need to be modeled accurately.

Study on identification of modal parameters of turbomachinery blade and impeller
Nihon Kikai Gakkai ronbunshu, 2020 To develop turbomachinery blades with high reliability, it is indispensable to verify the natural frequency, the damping, the resonant stress, etc. under operating condition, and utilize these data in the mechanical design of a new blade.
