Résumé / Abstract

Modern structural materials mostly exhibit anisotropic elastic behavior leading to complicated wave propagation phenomena. To ensure the reliability of ultrasonic nondestructive testing techniques, these material properties, as well as the influence of microstructural inhomogeneities and the effects of nonplanar surfaces and interfaces on ultrasonic wave propagation, have to be taken into account. In this respect, mathematical modeling provides an efficient method of assisting analysis. This paper presents two analytical approaches that are well suited for performing ultrasonic wave propagation and scattering simulations for complex structured media on a personal computer. Results for both isotropic materials, including curved interfaces, and for anisotropic media, such as composites and weld material, are presented. The simulation of transducer field profiles, the propagation of time dependent rf signals and the scattering of ultrasound at discontinuities are addressed.
