Description
| - Nonlinear parameters obtained by Nonlinear Elastic Wave Spectroscopy (NEWS) NDT techniques can give us better information about incipient damage zones than linear ones. Some limitations of NEWS methodology are given by difficulties with more precise defects location when global excitation of larger or more complicated structures is applied. To overcome these constraints, further developments of NEWS techniques referred as nonlinear pseudo-tomography or tomography defects imaging are described in the paper. Two NEWS methods are considered: Nonlinear Wave Modulation Spectroscopy (NWMS) and Nonlinear Time Reversal Mirrors (NLTRM) with ESAM and DORT processing. Both procedures use transducer arrays, allowing localization of damaged zones. Testing results, obtained on metallic and concrete parts illustrate performance of both procedures.
