    • Acoustic Scattering in an Isogeometric Framework 

      Venås, Jon Vegard (Doctoral theses at NTNU;2019:355, Doctoral thesis, 2019)

    • Exact 3D scattering solutions for spherical symmetric scatterers 

      Venås, Jon Vegard; Jenserud, Trond (Journal article; Peer reviewed, 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 ...

    • Isogeometric analysis of acoustic scattering 

      Venås, Jon Vegard (Master thesis, 2015)
      Acoustic scattering has been thoroughly analyzed with the use of finite element analysis (FEA). The problem at hand is a coupled fluid-structure interaction problem on an unbounded domain, where an object of elastic material ...

    • Isogeometric Analysis of Acoustic Scattering using Infinite Elements 

      Venås, Jon Vegard; Kvamsdal, Trond; Jenserud, Trond (Journal article; Peer reviewed, 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 ...

    • Isogeometric analysis of acoustic scattering with perfectly matched layers (IGAPML) 

      Venås, Jon Vegard; Kvamsdal, Trond (Peer reviewed; Journal article, 2022)
      The perfectly matched layer (PML) formulation is a prominent way of handling radiation problems in unbounded domain and has gained interest due to its simple implementation in finite element codes. However, its simplicity ...

    • Isogeometric boundary element method for acoustic scattering by a submarine 

      Venås, Jon Vegard; Kvamsdal, Trond (Journal article; Peer reviewed, 2019)
      Isogeometric analysis with the boundary element method (IGABEM) has recently gained interest. In this paper, the approximability of IGABEM on 3D acoustic scattering problems will be investigated and a new improved BeTSSi ...
