"Nonlinear Wave Modulation Spectroscopy (NWMS) is one of Nonlinear Elastic Wave Spectroscopy (NEWS) methods proven as very sensitive to the variety of material damage ranging from distributed microdamage to single cracks. The experimental procedure consists of simultaneous excitation of a specimen by two harmonic waves with frequencies f 0 resp. f 1. Nonlinear parameters can be estimated by analysis of harmonic and intermodulation component dependencies in the response signal. By using the scaling relations, an universal way of description of nonlinear spectral components was derived. The results of theoretical analysis were supported by an experiment. A new approach of hysteretic nonlinearity evaluation was proposed."@en . "10.1121/1.4749240" . . "POMA" . "Nonlinear wave modulation spectroscopy: Quasistatic solution and experimental evidence"@en .
