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

, 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.

Internal Friction and Microstructure of Ti and Ti-Mo Alloys Containing Oxygen

Archives of Metallurgy and Materials, 2016
Ti-Mo alloys are promising materials for use as biomaterials, because these alloys have excellent corrosion resistance and a good combination of mechanical properties such as fatigue, low elastic modulus, hardness, and wear resistance.

Thermal diffusion dominates Cu enrichment in optically dark areas of Al-Cu-Mg alloys: mechanistic insights for fatigue resistance enhancement

Materials Research Express
Optically dark areas (ODAs) on fatigue fracture surfaces of Al-Cu-Mg alloys, linked to premature failure, exhibit Cu-rich nanoparticles and surface oxidation. The mechanism driving Cu enrichment in ODAs (between mechanical friction and thermal diffusion)

3D‐Printed Serial Snap‐Through Architectures for Programmable Mechanical Response

Advanced Engineering Materials, EarlyView.
A serial snap‐through architecture is realized using compact 3D‐printed von Mises truss units arranged in a staged cascade. Their geometry and boundary conditions program multistage mechanical responses with plateaux and re‐hardening regimes. An inverted‐compliance model predicts these behaviors and enables analytical design of programmable force ...
