The book introduces computational wave propagation methods developed over 40 years of research and covers NDE of isotropic, anisotropic and functionally graded materials. It discusses recent methods to enable enhanced computational efficiency for anisotropic materials. It offers an overview of need for and uses of NDE simulation and provides a basic understanding of ultrasonic wave propagation through continuum mechanics and detailed discussions on the techniques and know-how of six computational methods to simulate NDE experiments virtually. Pros and cons of each individual method are discussed and guidelines for selecting specific simulation methods for specific NDE scenarios offered.
