Analytical approaches to the modeling of elastic wave propagation in solids are difficult to apply in the ultrasonic nondestructive testing (NDT) systems, where one is interested in predicting realistic transducer signals from ultrasound interactions with complex defect shapes. This report presents a finite element formulation for an overall ultrasonic NDT. Viscous boundaries are introduced to limit the problem domain to part of a tested material. These make it possible to reduce computational costs.
