Review of Multiaxial Testing for Very High Cycle Fatigue: From ‘Conventional’ To Ultrasonic Machines [PDF]
Machines, 2020 Fatigue is one of the main causes for in service failure of mechanical components and structures. With the development of new materials, such as high strength aluminium or titanium alloys with different microstructures from steels, materials no longer have a fatigue limit in the classical sense, where it was accepted that they would have ‘infinite life’

Redesigning axial-axial (biaxial) cruciform specimens for very high cycle fatigue ultrasonic testing machines [PDF]
Heliyon, 2017 The necessity to increase performances in terms of lifetime and security in mechanical components or structures is the motivation for intense research in fatigue. Applications range from aeronautics to medical devices. With the development of new materials, there is no longer a fatigue limit in the classical sense, where it was accepted that the ...

Modeling and Testing on Material Removal Mechanism of Rotary Ultrasonic Machining
DEStech Transactions on Materials Science and Engineering, 2017 The technology of rotary ultrasonic machining is the combination of regular ultrasonic vibration and rotation motion. It applies a pre-load on the tool through tool head with an axial direction vibration and high rotation motion along with the ultrasonic system.
