Abstract

This paper discusses some important recent developments in quantitative non-destructive evaluation, more specifically in quantitative ultrasonics. The importance of measurement models is emphasized, and the interaction of ultrasound with cracks is discussed in some detail. Three examples are discussed, both from a theoretical and an experimental point of view. These are backscattering of body waves from a surface-breaking crack, reflection and transmission of surface waves by a surface-breaking crack and line-focus acoustic microscopy of a specimen containing a subsurface crack. Mathematical measurement models also play a useful role in the training of neural networks, as discussed by the example of backscattering from a surface-breaking crack.
