This paper investigates the effects of fretting wear on frictional contacts. A high frequency
friction rig is used to measure the evolution of hysteresis loops, friction coefficient and …

Motivated by the current demands in high-performance structural analysis, and by a need to
better model systems with localized nonlinearities, analysts have developed a number of …

This paper presents a comprehensive review of recent advancements in modelling
approaches, design strategies, and testing techniques applied to friction damping in …

Underplatform dampers are widely used in turbomachinery to mitigate structural vibrations
by means of friction dissipation at the interfaces. The modelling of such friction dissipation is …

Aeroengine manufacturers face fundamental limitations when correlating experimental
dynamic analysis with finite element method models. The source of inconsistency between …

Accurately predicting the nonlinear dynamic response of aero-engine components is critical,
as excessive vibration amplitudes can considerably reduce the operational lifespan. This …

It is an attractive research topic to propose some novel damping methods for rotors, and the
dry friction damping is probably an effective and stable method. In this paper, a control …

The experimental study of joint mechanics has been limited in its effectiveness due to the
high uncertainty associated with assemblies of sub-components. In particular, two …

This paper presents a general geometric theory of in-plane motion of underplatform
dampers as a function of blade neck deflection and the resulting platform kinematics. In …

Friction interfaces are unavoidable components of large engineering assemblies since they
enable complex designs, ensure alignment, and enable the transfer of mechanical loads …
