采用三种声探头结构，通过衍射水平极化横波（SH）透射法，对SS 400钢的室温循环拉伸疲劳进行了研究。线性分析的传播时间和振幅的剪切和纵向波与疲劳进程表明，线性行为取决于残余应力，归因于声弹性效应。具体而言，剪切波的传播时间增加，波幅随疲劳进展而降低。我们的研究结果还表明，波的传播路径变得更深的渐进疲劳。此外，当探头角度优化衍射，在疲劳断裂之前的长度的估计变化为0.61%。非线性分析结果表明，二次谐波β参数随着疲劳的进展而增加，对于最佳频率配置高达~ 800%;这归因于与位错相关的粘弹性效应的数量增加。所提出的方法显示了巨大的潜力，无损评价金属疲劳残余应力和位错变化的分析。
Three acoustic probe configurations were used to assess cyclic-tension fatigue in SS400 steel at room temperatureviaa diffracted horizontally polarized shear wave (SH) transmission method. Linear analysis of the propagation time and amplitude of shear and longitudinal waves with fatigue progression revealed that the linear behavior was governed by residual stress, attributed to the acoustoelastic effect. Specifically, the propagation time of the shear waves increased and the wave amplitude decreased with fatigue progression. Our results also revealed that the propagation paths of the waves became deeper with progressive fatigue. Additionally, when the probe angle was optimized for diffraction, the estimated change in the length prior to fatigue breakage was 0.61 pct. Nonlinear analysis results revealed that second harmonicβ-parameters increased as fatigue progressed, up to ~800 pct for the optimal frequency configuration; this was attributed to an increase in the number of dislocation-associated viscoelastic effects. The proposed approach shows great potential for nondestructive evaluation of metal fatigueviaparameter analysis of residual stress and dislocation variations.
