Abstract
The acousto-ultrasonic method was used for detecting gap-type debonding and close-type debonding of SRM composite shell. On the basis of comprehensive analysis of different debonding type and frequency domain waveforms, the power spectral centroid SWF method was put forward to characterize the debonding type. The experimental results show that the power spectral centroid SWF can effectively identify two types of debonding.关键词
