A Numerical Study on the Effect of Debris Layer on Fretting Wear

open access: yesMaterials, 2016
Fretting wear is the material damage of two contact surfaces caused by micro relative displacement. Its characteristic is that debris is trapped on the contact surfaces.

Fretting Fatigue Life Prediction for Aluminum Alloy Based on Particle-Swarm-Optimized Back Propagation Neural Network

open access: yesMetals
Fretting fatigue is a specific fatigue phenomenon. Due to the complex mechanisms and multitude of influencing factors, it is still hard to predict fretting fatigue life accurately, despite there being many works on this topic.

Viral Infection‐Inspired Autonomous Detection of Fusion‐Competent Viruses for Screening and Environmental Surveillance

open access: yesAdvanced Materials, EarlyView.
Inspired by viral entry mechanisms, the FUSION assay enables autonomous detection of respiratory viruses via membrane fusion–triggered CRISPR‐Cas13a activation. VEACON selectively fuses with fusion‐competent viruses, triggering fluorescence within confined vesicles.

In-Situ Fretting Wear Analysis of Electrical Connectors for Real System Applications

open access: yesJournal of Manufacturing and Materials Processing, 2019
The tribological behavior of electrical contacts, especially separable type electrical connectors at low contact loads, are considered. The reliability of these connectors has been a major concern due to the fretting phenomenon that can lead to an ...

Predicting the steady state thickness of passive films in order to prevent degradations of implant [PDF]

open access: yes, 2013
Some implants have approximately a lifetime of 15 years. The femoral stem, for example, should be made of 316L/316LN stainless steel. Fretting corrosion, friction under small displacements, should occur during human gait, due to repeated loadings and un ...

An energy description of wear mechanisms and its applications to oscillating sliding contacts [PDF]

open access: yes, 2003
To quantify wear rates, the Archard approach is classically applied. It relates the wear volume to the product of the sliding distance and the normal load.
