Abstract

The crack detection capability of the Vibro-Acoustic Modulation NDE technique is experimentally investigated over a broad range of ultrasonic frequencies. The generation of low frequency modes of the samples is performed using harmonic excitation applied by a shaker or by tapping. For both excitation methods the effect of different strain levels on the sideband activity is analyzed. The implementation of practical and reliable supports for testing the specimens is also considered in this study, as well as examples of results on industrial components.
