Modal Analysis Of High Frequency Acoustic Signal Approach For Progressive Failure Monitoring In Thin Composite Plates

During the past few decades, many successful research works have evidently shown remarkable capability of Acoustic Emission (AE) for early damage detection of composite materials. Modal Analysis of AE signals or Modal Acoustic Emission (MAE) offers a better theoretical background for acoustic emissi...
