Abstract

The wavelet analysis is adopted for dealing with the signal. The main subject is to calculate the dynamic response of sandwich board. Then the structure response signal is decomposed by wavelet tools after deducing the annoyance. The real-time monitoring for composite material is carried out by catching the damaging moment. The damage character is chosen by comparing the susceptibility with damage among response signals.
