Looking at wear of incomplete contacts in partial slip we start from an asymptotic description the contact tractions edges. We introduce distributed dislocations along zone to account for profile reduction due and find long-term time asymptote where is wholly stuck. The resulting stress field used crack tip intensity factors short edge cracks, which are useful predicting nucleation threshold.

This paper studies the corrosion behavior of B10 copper-nickel alloy in marine environment. Accelerated degradation test under marine environmental conditions was designed and performed based on the accelerated testing principle and the corrosion degradation mechanism. With the prolongation of marine corrosion time, the thickness of Cu₂O film increased gradually. Its corrosion product was Cu₂(O...

Nominally static contacts such as bolted or shrink-fit joints typically experience regions of microslip when subjected to oscillatory loading. This results in energy dissipation, reflected as apparent hysteretic damping of the system, and also may cause the initiation of fretting fatigue cracks. Early theoretical studies of the Hertzian contact problem by Cattaneo and Mindlin were confirmed exp...

Fretting fatigue is a damage process that occurs when two surfaces in contact with each other are subjected to relative micro-slip, causing reduced life respect the plain case. has now been studied deeply for over 50 years, but still no univocal design approach universally accepted. This review presents literature study involves three main types of mechanical joint affected by fretting (press-f...
