摘要

In recent years the use of guided waves and nonlinear acoustic techniques has increased tremendously for structural health monitoring applications. Guided waves are being used for defect detection, acoustic source localization, and damage quantification for a wide range of structures in aerospace, civil, mechanical, electronic, and biomedical engineering. Guided waves provide an ideal compromise between sensitivity and range because they can provide small enough wavelengths to detect small damage, while exploiting the waveguide geometries to travel long distances.
