In order to compute continuous wave (cw) ultrasonic wave fields in complex media, where analytical approaches are extremely difficult, numerical simulations on large computational grids must be employed. The use of a time domain code, normally used f

Full-field visualization of ultrasound interacting with a material defect allows the dynamic stress (strain) field to be investigated. Many real materials and structures contain defects such as voids, inclusions and cracks throughout their volume whi

Current ultrasonic tomography methods do not properly handle cases involving large refraction, mode conversion, strong scattering, or finite apertures. To account for these different effects, a method has been developed utilizing a very efficient cod

When laminae are smaller than the wavelengths that measure them, a composite appears homogeneous and anisotropic. Composites are often subjected to high temperature gradients during their fabrication which can result in residual stresses, and damage

In anisotropic media, the direction of energy propagation does not necessarily coincide with the wave normal, i.e. the energy flux vector does not coincide with the wave normal. Since, experimentally, one measures group velocity not phase velocity, o

A perturbative treatment of ultrasonic Rayleigh wave propagation is applied to investigate the case of an initally deformed metal plate, assumed to be homogeneous and to consist of an orthotropic disribution of cubic crystallites. Time‐of‐flight
