Exact 3D scattering solutions for spherical symmetric scatterers
Venås, Jon Vegard; Jenserud, Trond (2018)In this paper, exact solutions to the problem of acoustic scattering by elastic spherical symmetric scatterers are developed. The scatterer may consist of an arbitrary number of fluid and solid layers, and scattering with ... -
Generalization and stabilization of exact scattering solutions for spherical symmetric scatterers
Venås, Jon Vegard; Jenserud, Trond (2022-08-29)In a previous work the authors described a fast high-fidelity computer model for acoustic scattering from multi-layered elastic spheres. This work is now extended with a scaling strategy significantly mitigating the problem ... -
Isogeometric Analysis of Acoustic Scattering using Infinite Elements
Venås, Jon Vegard; Kvamsdal, Trond; Jenserud, Trond (2018)Isogeometric analysis (IGA) has proven to be an improvement on the classical finite element method (FEM) in several fields, including structural mechanics and fluid dynamics. In this paper, the performance of IGA coupled ...
