    • Analysis of the Stuhmiller blast injury model 

      Teland, Jan Arild; Skriudalen, Stian (2013-06-04)
      The Stuhmiller model for blast wave injury has been studied. Although it has not been documented well in literature, we were able to program the model in Matlab and study some of its properties. It turned out that the ...

    • Development of material models for semi-brittle materials like tungsten carbide 

      Moxnes, John F.; Teland, Jan Arild; Skriudalen, Stian; Bergsrud, Svein Morten; Sundem-Eriksen, Lasse; Fykse, Haakon (2010)
      Tungsten carbide is a very special material that exhibits both brittle and ductile properties. While purely brittle and ductile materials in general are well understood, a theory for describing the properties of a hybrid ...

    • Materialer for ballistisk beskyttelse 

      Skriudalen, Stian; Dullum, Ove; Bergsrud, Svein Morten; Wulvik, Erik (2009)
      Metaller har fra tidenes morgen vært brukt både som våpen og beskyttelse. Teknologi for bearbeiding ble tidlig utviklet, og råvarene var tilgjengelige. Metaller er de materialene, innenfor beskyttelsessammenheng, med ...

    • Misalignment effects using blast pencil probes 

      Skriudalen, Stian; Skjold, Arild; Hugsted, Bjørn; Teland, Jan Arild; Huseby, Morten (2014-02-12)
      This report investigates the use of blast pencil probes and the effect on the pressure-time history when having a non-optimized alignment of the pressure gauges, the so-called misalignment effect. This may be of special ...

    • Shock attenuation experiments using a Hopkinson bar method : summary of experimental results 

      Teland, Jan Arild; Skriudalen, Stian (2009)
      Close-in attenuation of the pressure wave from a detonation is desirable in several applications. Porous materials are often assumed to have good shock damping properties. In this report an experimental set-up using a ...

    • Simple methods of estimating the hazardous area for a multiple blast situation 

      Skriudalen, Stian; Teland, Jan Arild; Skjold, Arild (2012-08-24)
      Active Protection Systems (APS) may cause injury to personnel nearby. To estimate the potential injury from an APS we examine the general case of two charges detonating in relative proximity. Three different methods for ...

    • Testing av blindgjengere fra 12,7 mm og 20 mm MP-ammunisjon mot åpen ild - risiko for utilsiktet oppvarming 

      Skriudalen, Stian; Fykse, Haakon; Dullum, Ove (2000)
      Gjennom de siste tiårene har MP-ammunisjon i kaliber 12,7 mm og 20 mm blitt mer og mer utbredt i Forsvaret. Denne ammunisjonstypen inneholder en liten, men ikke ufarlig, mengde sprengstoff. I forbindelse med rydding og ...
