• Deconfliction and Surface Generation from Bathymetry Data Using LR B-splines 

      Skytt, Vibeke; Harpham, Quillon; Dokken, Tor; Dahl, Heidi Elisabeth Iuell (Chapter, 2017)
      A set of bathymetry point clouds acquired by different measurement techniques at different times, having different accuracy and varying patterns of points, are approximated by an LR B-spline surface. The aim is to represent ...
    • Isogeometric Analysis 

      Dokken, Tor; Kvamsdal, Trond; Pettersen, Kjell Fredrik; Skytt, Vibeke (Journal article; Peer reviewed, 2010)
      NURBS (Non Uniform Rational B-Spline) curves and surfaces have been used extensively in Computer Aided Design (CAD) in the last two decades but not in Finite Element Analysis (FEA). Isogeometric analysis [6], introduced ...
    • Parametric Shape Optimization for Combined Additive–Subtractive Manufacturing 

      Tamellini, Lorenzo; Chiumenti, Michele; Altenhofen, Christian; Attene, Marco; Barrowclough, Oliver Joseph David; Livesu, Marco; Marini, Federico; Martinelli, Massimiliano; Skytt, Vibeke (Journal article; Peer reviewed, 2019)
      In industrial practice, additive manufacturing (AM) processes are often followed by post-processing operations such as heat treatment, subtractive machining, milling, etc., to achieve the desired surface quality and ...
    • Trivariate Spline Representations for Computer Aided Design and Additive Manufacturing 

      Dokken, Tor; Skytt, Vibeke; Barrowclough, Oliver Joseph David (Journal article; Peer reviewed, 2018)
      Digital representations targeting design and simulation for Additive Manufacturing (AM) are addressed from the perspective of Computer Aided Geometric Design. We discuss the feasibility for multi-material AM for B-rep based ...
