... Parametric Stress Modulation Effect on Surface Wave Interaction with Cracks . ... This paper addresses experimental and theoretical aspects of parametric effects on a surface acoustic wave interacting with a partially closed fatigue crack emanating from a surface cavity. ... It turns out that the application of low amplitude modulation load enhances the sensitivity of detection of partially closed fatigue cracks helping to discriminate the evolving crack from a volumetric flaw. ...
