Abstract
- Non-linear ultrasonic parameter β and acoustic emission signals of ultrasonic fatigue testing were analyzed by using Laser Doppler Vibrometer and continuous AE waveform analysis system. Notched specimens of the high-strength low-alloy steel were prepared for the ultrasonic fatigue testing with exciting vibration frequency of 20 kHz. The AE events for each broken specimens were detected prior to the increase of β parameter. [ABSTRACT FROM AUTHOR]
