Nonlinear Vibro-Acoustic Nondestructive Testing Technique
Chapter
Abstract
Conventional active acoustic methods of NDT are based on the principles of linear acoustics1,2. These include effects of reflection, scattering, transmission, absorption of probe acoustic energy. The presence of a defect leads to phase and/or amplitude variation of received signals while the frequencies of the received signals are the same as of emitted probe signals.
