A thorough understanding of the mechanics of wave propagation is critical for the quantitative nondestructive evaluation of structural components. This is of special importance when considering guided waves and how they are influenced by geometric features. Analytical solutions are available for relatively simple geometries, like plates or perfect annular structures. However, there are no closed form solutions available for more complicated geometries that are present when interrogating actual structural components. As a result, other, more robust solution methodologies are needed.
