Machine-Learning-Based Methods for Acoustic Emission Testing: A Review
Applied Sciences, 2022 Acoustic emission is a nondestructive control technique as it does not involve any input of energy into the materials. It is based on the acquisition of ultrasonic signals spontaneously emitted by a material under stress due to irreversible phenomena ...

Fretting Fatigue Behaviour of Alloy Steel in the Very High Cycle Region [PDF]
MATEC Web of Conferences, 2019 It is well known that fretting fatigue strength is much lower than the fatigue strength of smooth specimens and the fatigue limit disappears. Many studies on fretting fatigue have been reported but most of the studies have not cover fatigue properties in
