    • Inverse modeling of penetration into 12.7 cartridges 

      Moxnes, John F.; Nilssen, Jan R. (2002)
      In this article a study of the forces caused by penetration of steel penetrators into cartridges of brass has been carried out. Experimental data was compared with simulations using the Nike-2D code and with solutions ...

    • Material properties of Wolfram Carbide established by using a bending test 

      Nilssen, Jan R.; Moxnes, John F.; Sagsveen, Bendik (2002)
      In this article a study of the stresses caused by bending of penetrators made of Wolfram Carbide has been carried out. Experimental data was compared with simulations using the Marc-3D code and with solutions from a simple ...

    • Material properties of wolfram carbide established by using a simple indentation test 

      Moxnes, John F.; Nilssen, Jan R.; Frøyland, Øyvind; Friis, Eva (2003)
      In this article a study of the fracture stress caused by indentation of wolfram carbide penetrators into steel blocks has been carried out. Experimental data was compared with simulations using the Nike-2D code and with ...

    • Testing of the Chemical, Atomic and Toxic compound Surveillance System - CATSS 

      Tørnes, John Aasulf; Prydz, Petter Andre; Nilssen, Jan R.; Sagsveen, Bendik (2007)
      A first prototype of the Chemical, Atomic and Toxic compound Surveillance System (CATSS) has been developed at FFI. The prototype has been tested during winter conditions at FFI and has been field tested at Ørland Main ...
