... reached its minimum value. Another nonlinear ultrasonic testing, namely, sideband peak count index (SPC-I) showed a similar variation when correlated with X parameter. It is concluded that both the normalized second harmonic amplitude and the sideband peak count index can be used as an indicator...

... for damage characterization. Linear ultrasonic parameters such as the time-of-flight (related to wave velocity) and signal amplitude (related to wave attenuation) were recorded. The nonlinear ultrasonic parameter, Sideband Peak Count—Index (SPC-I), was obtained by a newly developed nonlinear analysis...
