Inhomogeneous P- and S-wavefields radiated into isotropic elastic solids
Viggen, Erlend Magnus; Arnestad, Håvard (Chapter, 2022)A vibrating surface in contact with a solid material will generate P- and S-waves in the solid. When the surface vibration is spatially attenuated, we must take into account that the generated waves are always inhomogeneous. ... -
Modelling acoustic radiation from vibrating surfaces around coincidence: Radiation into fluids
Viggen, Erlend Magnus; Arnestad, Håvard (Peer reviewed; Journal article, 2023)It is well-known that vibrating surfaces generate sound waves in adjacent fluids. According to the classical radiation model, the nature of these waves depends on whether the vibration’s phase speed cv is above (supersonic) ...
