Threaded fasteners are vastly used in the industry due to ease of mounting and dismounting
and flexibility of design. Nonetheless, several researchers indicate that most failures …

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 …

Subjected to dynamic excitations, bolted joint interfaces exhibit nonlinear characteristics that
significantly affect the dynamic response of assembled structures. In this paper, a novel …

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

Mastering physical phenomena taking place in aircraft engines is a key objective for
manufacturers. Contact interfaces with dry friction in bladed-disks allows decreasing the …

Bolt connection plays an important role in assembly structures. Under long-term vibrations,
bolted joint interface will change due to fretting-induced friction and wear behavior. This …

This paper presents a novel test rig to study the effect of fretting wear and of the contact
surface evolution on the forced response of systems with dry friction contact. This rig allows …

The present article summarizes the submissions to the Tribomechadynamics Research
Challenge announced in 2021. The task was a blind prediction of the vibration behavior of a …

The study of contact is an engineering pursuit that spans multiple disciplines and scales.
Structural dynamics, as well as aspects of nonlinear dynamics and vibrations, is concerned …

During the working process of the system of hydraulic opposing cylinders controlled by a
servo valve, the fluid equivalent stiffness changes dynamically due to the pressure pulsation …
