  5. 4. Investigating strains on the Oseberg ship using photogrammetry and finite element modeling

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Andreas Eriksson; Erik Thermaenius; [2020]
    Keywords : Oseberg ship; strain; strain analysis; mechano-sorptive strains; Delaunay triangulation; finite element analysis;

    Abstract : The Oseberg ship is known as one of the finest surviving artifacts from the Viking age, with origins dated back to the 800s. The ship has been displayed in the Viking ship museum in Oslo since 1926. The nearly 100 years on museum display along with the over 1000 years it was buried has weakened the structure of the ship.
