CO2 pipeline integrity: A new evaluation methodology
Berstad, Torodd; Dørum, Cato; Jakobsen, Jana Poplsteinova; Kragset, Steinar; Li, Hailong; Lund, Halvor; Morin, Alexandre; Munkejord, Svend Tollak; Mølnvik, Mona Jacobsen; Nordhagen, Håkon Ottar; Østby, Erling (Journal article; Peer reviewed, 2011)A coupled fluid-structure model for pipeline integrity simulations has been developed. The pipe material and fracture propagation have been modelled using the finite-element method with a local fracture criterion. The ... -
Numerical simulations of material mismatch and ductile crack growth
Østby, Erling (Doktoravhandlinger ved NTNU, 1503-8181; 2002:13, Doctoral thesis, 2002)Both the global geometry and inhomogeneties in material properties will influence the fracture behaviour of structures in presence of cracks. In this thesis numerical simulations have been used to investigate how some ...
