A Crack Size Quantification Method Using High-Resolution Lamb Waves [PDF]

open access: yesSensors, 2021
Traditional tone burst excitation cannot attain a high output resolution, due to the time duration. The received signal is much longer than that of excitation during the propagation, which can increase the difficulty of signal processing, and reduce the ...

Mechanism of crack branching in the fatigue crack growth path of 2324-T39 Aluminium alloy [PDF]

open access: yesFracture and Structural Integrity, 2016
The crack growth behavior in 2324-T39 aluminium alloy was experimentally investigated. Two types of crack branching were observed. The mechanism of an uncommon crack branching which results from the link up of secondary crack with the main crack was ...

Fractal scaling and crack-size effects on creep crack growth

open access: yesStrength, Fracture and Complexity, 2020
Scaling effects on the creep crack growth behaviour are investigated by analyzing the results of compact tension (CT) tests on different-sized notched steel specimens appearing in the literature. Creep crack growth rate data are correlated to the elastic stress-intensity factor in terms of a Paris-type law, da∕dt = C0Kq, where C0 turns out to be a ...
