This book solves scattering problems for elastic waves in solids using analytical and semi-analytical approaches, methods that are useful for simply shaped obstacles at low and intermediate frequencies. The obstacles include circles, spheres, and straight and circular cracks. Both isotropic and some anisotropic solids are treated. The book concludes with an introduction to applications in ultrasonic non-destructive evaluation and material characterization. The problems taken up are of interest in themselves, but also have the potential to act as benchmark solutions for numerical methods like FEM.As such, this is the broadest existing book in this area. It should be of interest to researchers and PhDs working with modelling approaches in several applied areas such as ultrasonic non-destructive testing and material characterization. The book is also relevant to problems in geophysics.
