Abstract This paper presents a novel test rig to study the effect of fretting wear and contact surface evolution on forced response systems with dry friction contact. allows simulating contacts similar type present between shrouds at blade tip. Several research groups have been studying how affects dynamic mechanical systems, developing numerical prediction tools that consider nonlinearity. The...

INTRODUCTION: In current total hip arthroplasty, modularity between the head-neck connection of the femoral stem is well established. More recently, implants with an additional modular connection between the neck and stem have become more popular. The ability to adjust the head centre relative to the stem axis intraoperatively, by connecting the neck in different positions, guarantees high vers...

Fretting damage phenomenon often appears in the interference fit assembly. The finite element model of hollow shaft and shaft sleeve was established, and the equivalent stress and contact stress were computed after interference assembly. The assembly body of hollow shaft and shaft sleeve was in whirling bending load, and the contact status (sticking, sliding, and opening) and the distribution o...

Tribocorrosion in taper junctions of retrieved anatomic shoulder arthroplasty implants was evaluated. A comparison of the tribocorrosion between cobalt-chromium and titanium alloy stems was conducted and the observations were correlated with the individual's clinical data. Adverse effects caused by metal debris and subsequent elevated serum metal ion levels are frequently reported in total hip ...
