    • 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 ...

    • Environmental toxicology of blast exposures: Injury metrics, modelling, methods and standards 

      Leggieri, Michael J; Bieler, Dan; Bjarnason, Stephen; Cernak, Ibolja F; Franke, Axel F; Kirkman, Emrys; Martineau, L; Orru, Hans; Ouellet, S; Philippens, M; Risling, MG; Sarron, JC; Skriudalen, Stian; Teland, Jan Arild; Watts, Sarah A; Gupta, RK (2018)

    • Experimental and numerical study of the fragmentation of expanding warhead casings by using different numerical codes and solution techniques 

      Moxnes, John Fredrik; Prytz, Anne K.; Frøyland, Øyvind; Klokkehaug, Siri; Skriudalen, Stian; Friis, Eva; Teland, Jan Arild; Dørum, Cato; Ødegårdstuen, Gard (2014)
      There has been increasing interest in numerical simulations of fragmentation of expanding warheads in 3D. Accordingly there is a pressure on developers of leading commercial codes, such as LS-DYNA, AUTODYN and IMPETUS Afea, ...

    • Guidelines for conducting epidemiological studies of blast injury 

      Bieler, Dan; Cernak, Ibolja F; Martineau, L; Bjarnason, Stephen; Franke, Axel F; Kirkman, Emrys; Leggieri, Michael J; Orru, Hans; Ouellet, S; Philippens, M; Risling, MG; Sarron, JC; Skriudalen, Stian; Teland, Jan Arild; Watts, Sarah A; Gupta, Raj (2018)
      Blast injuries are often caused by more than one mechanism, do not occur in isolation, and typically elicit a secondary multi-system response. Research efforts often do not separate blast injuries caused by blast waves ...

    • Guidelines for reproducing blast exposures in the laboratory 

      Josey, Tyson; Ouellet, S; Bieler, Dan; Cernak, Ibolja F; Franke, Axel F; Gupta, Raj; Kirkman, Emrys; Leggieri, Michael J; Orru, Hans; Philippens, M; Risling, M.; Sarron, JC; Skriudalen, Stian; Teland, Jan Arild; Watts, Sarah A; Bjarnason, Stephen (2018)

    • Guidelines for using animal models in blast injury research 

      Watts, Sarah; Kirkman, Emrys; Bieler, Dan; Bjarnason, Stephen; Franke, Axel; Gupta, Raj Kumari; Leggieri, Michael J.; Orru, Hans; Ouellet, Simon; Philippens, Mat M. G. M.; Sarron, Jean-Claude; Skriudalen, Stian; Teland, Jan Arild; Risling, Mårten; Cernak, Ibolja (2018)
      Blast injury is a very complex phenomenon and frequently results in multiple injuries. One method to investigate the consequences of blast injuries is with the use of living systems (animal models). The use of animals ...

    • 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 ...

    • On the study of ricochet and penetration in sand, water and gelatin by spheres, 7.62 mm APM2, and 25?mm projectiles 

      Moxnes, John Fredrik; Frøyland, Øyvind; Skriudalen, Stian; Prytz, Anne K.; Teland, Jan Arild; Friis, Eva; Ødegårdstuen, Gard (2016)
      We examine the ricochet and penetration behavior in sand, water and gelatin by steel spheres, 7.62 mm APM2 and 25 mm projectiles. A threshold impact angle (critical angle) exists beyond which ricochet cannot occur. The ...

    • 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 ...

    • Strain rate dependency and fragmentation pattern of expanding warheads 

      Moxnes, John Fredrik; Prytz, Anne K.; Frøyland, Øyvind; Skriudalen, Stian; Børve, Steinar; Ødegårdstuen, Gard (2014-12-22)
      For the characterization of the behaviors of a metal material in events like expanding warheads, it is necessary to know its strength and ductility at high strain rates, around 104 e105 /s. The flyer plate impact testing ...

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