Originální abstrakt

The nonlinear ultrasonic testing is quite prolific method but it has some limitations in practical testing, mainly for inhomogeneous materials. Materials with undamaged structure are essentially linear in their response, while the same material, when damaged, becomes highly nonlinear. In spectrograms is it represented by harmonics and sideband generation. The nonlinear ultrasonic spectroscopy is evolved as a new way to improving the NDT and it offers some new possibilities for the NDT. This is the basis for nonlinear wave diagnostics of damage, methods which are remarkably sensitive to the detection and progression of damage in materials. This paper offers analysis, principles and basic methods for nonlinear ultrasonic spectroscopy and also contains their limitations.
