,Overview—Nonlinear Ultrasonic Characteristics,erial or defects, which typically include higher harmonic generation, sub-harmonic generation, nonlinear resonance and nonlinear frequency-mixing. In this book, such nonlinear interactions are divided into two categories, namely the material elastic nonlinearity and the contact acoustic nonlinearity

Measurement of Nonlinear Guided Wavesmation is related to the material‘s microstructure, which in turn influences the strength properties. However, the dispersive nature of guided waves makes their nonlinear characteristics more complicated than those of bulk waves. This chapter strives to describe nonlinear features of guided wave pro

Nonlinear Acoustic Measurements for NDE Applications: Waves Versus Vibrationsmaterials. The nonlinear approach to ultrasonic NDE is concerned with nonlinear material response, which is inherently related to the frequency changes of the input signal, and is a new technology for monitoring of deterioration in material properties and diagnostics of damage. The application field

Nonlinear Frequency-Mixing Photoacoustic Characterisation of a Cracka pair of laser beams intensity-modulated at two different frequencies. The first laser beam, intensity modulated at a low frequency ., generates a thermoelastic wave which modulates the local crack rigidity up to complete closing/opening of the crack, corresponding to crack breathing.
