    • Minute-scale period oscillations of the magnetosphere 

      Børve, Steinar; Sato, Hiroatsu; Pecseli, Hans; Trulsen, Jan Karsten (2011)
      Oscillations with periods on the order of 5–10 min have been observed by instrumented spacecrafts in the Earth's magnetosphere. These oscillations often follow sudden impacts related to coronal mass ejections. It is ...

    • Simulation of natural fragmentation of rings cut from warheads 

      Moxnes, John Fredrik; Børve, Steinar (2015)
      Natural fragmentation of warheads that detonates causes the casing of the warhead to split into various sized fragments through shear or radial fractures depending on the toughness, density, and grain size of the material. ...

    • 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 ...
