Measurement of interface pressure in interference fits [PDF]
, 2005 When components such as bearings or gears are pressed onto a shaft, the resulting interference induces a pressure at the interface. The size of this pressure is important as many components fail because fatigue initiates from press-fit stress ...

Advanced Engineering Materials, EarlyView.The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Ultrasonic fatigue tests on the Inconel alloy 718
Procedia Structural Integrity, 2020 Abstract Ultrasonic fatigue tests were carried out on the Inconel alloy 718 on pre-corroded and specimens without pre-corrosion. At high applied stress (up to 746 MPa) the specimens without pre-corrosion show fatigue endurance higher compared with the pre-corroded specimens with a factor of 10; whereas at low stress level (close to 510 MPa), the ...
