C. W. Schwingshackl, Auteur ; E. P. Petrov, Auteur ; D. J. Ewins, Auteur |The design of high cycle fatigue resistant bladed disks requires the ability to predict the expected damping of the structure in order to evaluate the dynamic behavior and ensure structural integrity. Highly sophisticated software codes are avai[...]
