Abstract
Compared with the mostly concerned ultrasonic guided wave-based damage detection for thin plate-like structures, this paper focuses a diagnosis procedure on thick steel beams with thickness of 34 mm. The procedure for producing fatigue crack as well as the PZT transducers layout, were first described, and some parameters, such as the frequency and the cycle numbers of the diagnostic waveform, were discussed. Both "pulse-echo" and "pitch-catch" approach were adopted for predicting the crack location and severity. The results demonstrate that guided waves-based damage identification approach can also be applied to fatigue crack detection in relatively thick structures.
