    • Rapid Autodyn-3D penetration simulations using a virtual target 

      Olsen, Åge Andreas Falnes; Teland, Jan Arild (2002)
      By taking advantage of the possibilities for developing user subroutines in Autodyn-3D, we implement a method that uses a virtual target to decrease runtimes for 3D problems by several orders of magnitude. The new method ...

    • Miljømessige vurderinger av blyfri ammunisjon - utvaskingsforsøk med forurenset jord 

      Strømseng, Arnljot; Ljønes, Marita (2002)
