Description

Files "cpchnorm_*.csv" are recorded from the pristine plate as the baseline signal. While files "cpchdama_*.csv" are captured after the simulated damage (i.e., added mass) is introduced. In these files, the first column is the sampling time, the second one is the original chirp excitation, and the third one is the Lamb wave response captured at the receiver (i.e., PZT). The 20 files at the same state are averaged to improve the signal-to-noise ratio, and the toneburst response is extracted from the averaged signal.
