摘要: Guided waves scattered from defects in solid material might contain significant information about those defects. The major goal of non-destructive evaluation is to interpret the ultrasonic signatures these Scattering Lamb a normal, surface breaking defect considered this study. Reflection and transmission factors modes are used reconstruct size flaws. crack have been investigated [1–7]. Resonance phenomena for parallel plate [5,6]. In study, boundary element method combined with normal mode technique [1,8] study relationship between parameters incident mode. Irregular behavior reflection coefficient special classification.
