Description

The requirements of nondestructively inspecting cast steels, weldments, composites, and other inherently anisotropic materials have necessitated research aimed at better understanding ultrasonic wave propagation in these materials. Theoretical modeling can play an important role in the study of the unique effects, such as beam skew and excess beam divergence, which anisotropic materials have on ultrasonic transducer beams. The predictions of valid models can be used to help interpret nondestructive measurements and to help guide the choice of nondestructive inspection procedures by identifying configurations with the most promise of success. Much recent work has been devoted to this subject (for example Refs. [1–5]).
