Study on delamination detection in CFRP using wavelet signal singularity analyses

摘要

In this paper, wavelet analyses are used to identify the delamination detects in the CFRP plates using the signals from surface-mounted piezoceramics. Through the experiments of the CFRP beams, It is observed that the local response signals' singularities are strongly related to the delamination location and size between the generator and transducer.
