Abstract:
This paper presents a novel approach utilizing nonlinear ultrasonic guided waves for the detection and evaluation of high-cycle fatigue damage in aluminum alloy plates. Through high-cycle fatigue testing, specimens with varying degrees of fatigue damage were created and evaluated using ultrasonic-guided wave measurement technology. The integration of time-frequency analyses effectively reduced the impact of wave dispersion and resonance effects, establishing a reliable operational frequency bandwidth. The results identified a positive correlation between the amplitude of odd harmonic components caused by hysteresis nonlinearity and fatigue crack length, while an inverse correlation was observed with specimen resonance frequency. The results confirm the high sensitivity and accuracy of this approach for early fatigue damage detection, offering a significant advancement in the non-destructive evaluation of engineering structures and a foundation for structural failure prevention.
