Crack growth behaviour of aluminium wrought alloys in the Very High Cycle Fatigue regime [PDF]
MATEC Web of Conferences, 2018 Investigations have shown that in the regime of Very High Cycle Fatigue (VHCF) “natural” crack initiation often takes place underneath the material surface leading to crack propagation without contact to atmospheric components.

Acoustic emission study of fatigue crack propagation in Q345R
工程科学学报, 2015 The acoustic emission signals of fatigue crack propagation in Q345R,which is the typical representative of common steel for pressure vessels,were investigated in detail to construct a relationship between fatigue and acoustic emission.

Bending fatigue crack propagation behavior of U75V heavy rail steel
Cailiao gongcheng, 2023 In order to clarify the fatigue crack propagation behavior of pearlitic rail, the three-point bending fatigue crack propagation rate of U75V heavy rail steel in rolling state and heat treatment state was measured.

Analysis on Fatigue Crack Initiation and Fatigue Crack Propagation in a Gear
SMART MOVES JOURNAL IJOSCIENCE, 2017 An effective gear design balances strength, durability, reliability, size, weight and cost. Because of the advantage of gear, gearbox was used widely. But its fault also brought many losses of the production and society. It was necessary to research and analysis on the dynamical behavior of the gear system.
