Nonlinear vibro- acousto- ultrasonic waves for fatigue cracking detection in key rail components
thesisposted on 2021-02-20, 13:23 authored by YU FUNG LEE
Safety monitoring of the ageing train structures has always been a major challenge to the rail industry. This thesis develops a damage detection system based on nonlinear ultrasonic wave to identify fatigue crack at early stage on bogie frame to avoid catastrophic failure.
