Abstract: Abstract In turbomachinery applications, rotating bladed disks (blisks) are often subject to high levels of dynamic loading, such as traveling wave excitations, which result in large response amplitudes at resonance. To prevent premature high cycle… read more here.

Abstract: Abstract In operation, blisks are subject to dynamic loading, which result in large response amplitudes near resonance. To reduce the response level and prevent damages caused by high cycle fatigue, friction damping sources are introduced… read more here.
