https://doi.org/10.1007/978-1-4613-1947-4es different commercially available testing systems have been developed and long propagation distances up to 100 m have been achieved. Careful selection of guided wave mode and excitation frequency allows the minimization of attenuation due to viscoelastic coatings and in buried pipelines. Synthetic

Tom J. Mabry,K. R. Markham,M. B. Thomascations are described. First, NRS was used to quantify thermal damage of carbon fiber reinforced polymers (CFRP) samples. The nonlinear parameters are much more sensitive to the microdamage than linear properties, such as a change of the Young’s modulus or the damping coefficient. Moreover, the NRS

Next is a discussion of the analysis of white light fringes used to measure special features of objects, i.e., thick and thin films, harmonically moving objects, involving surface features that are challenging to measure (dissimilar materials, complicated geometry, etc.).

Physical Basis for Ultrasonic Acousticsn terms of potentials and the coherence condition (aka Snell’s law for ultrasonics) is derived. The general solution is deduced under the assumption that the incident P and SV waves are coherent with each other. When the P and SV waves are not coherent to each other, the general solution is made spe

Ultrasonic Wavefield Imaging methods must be applied to the wavefield data to yield quantitative information concerning the detection, localization, and characterization of damage. The focus of this chapter is to provide an introduction to the acquisition and analysis of wavefield data in the context of three case studies: imp
