Abstract
The NDE of real-life situations is based on elastic (ultrasonic) wave propagation, diffraction and scattering in dissipative inhomogeneous isotropic or anisotropic media. Physical phenomena of elastic waves are described by linear Cauchy’s equation of motion and equation of deformation rate [1, 2]. Interpretation of the very complicated behavior of elastic waves, especially in inhomogeneous anisotropic media, requires powerful computational tools to model and study advanced NDT situations. Such a tool is the well-established Elastodynamic Finite Integration Technique (EFIT) basically formulated by Fellinger [3, 4]. Recently, EFIT has been extented to simulate elastic waves in dissipative (viscoelastic) and homogeneous anisotropic media [5, 6].
