Nonlinear Acoustic NDE – Qualitative and Quantitative Effects

Abstract:

Article Preview

The recent results in constructing the mathematical basis of nonlinear acoustic techniques for NDE of inhomogeneous materials are discussed. These include microstructural materials and materials with weakly or strongly changing properties of specimens (structural elements) under inhomogeneous prestress. The idea is to extract additional information from nonlinear and dispersive effects of wave propagation. Novel concepts are introduced: (i) the analysis of dispersive effects; (ii) the analysis of two counter-propagating nonlinear waves.
