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.
