Abstract
A computational fast ultrasonic modeling code based on the superposition of Gaussian beams is applied to clad-component and weld geometries. In particular the approach accounts for the propagation through the isotropic/anisotropic layers and the reflection/refraction process at the interfaces. In describing piston transducers, a ten-term Gaussian beam solution is used.
