Scattering of elastic waves by an anisotropic sphere
Licentiate thesis, 2021
The T matrices may be used to solve more complicated problems like the wave propagation in polycrystalline materials. The attenuation and wave velocity in a polycrystalline material with randomly oriented transversely isotropic grains is thus investigated. These quantities are calculated analytically using the simple theory of Foldy and show a very good correspondence for low frequencies with previously published results and numerical computations with FEM.
