    • Oxidation and carburisation steel in gun barrels 

      Frøyland, Øyvind; Moxnes, John F. (2006)
      In this report a theoretical and experimental study of some basic gun barrel erosion mechanisms have been carried out. The theoretical analysis of the reaction mechanisms leading to erosion is based on the minimalization ...

    • Plasticity computation in hydrocodes compared with analytical theory 

      Teland, Jan Arild; Moxnes, John F. (2000)
      Associated analytical plasticity theory is reviewed and compared with the approach to plasticity used in hydrocodes such as Autodyn and Dyna. In general, the two methods are seen to be quite different, but for certain special ...

    • Studies of wear charactistics of three different gunpowder gases 

      Frøyland, Øyvind; Moxnes, John F. (2006)
      In this report a study of the gun barrel wear characteristicsof three different gunpowders are performed. The three different gunpowders are: Bofors NC 1214 NEXPLO (NEXPLO), BOFORS NC 1214 EURENCO (EURENCO) and PB Clermont ...

    • Tensile tests of Wolfram Carbide hard cores 

      Frøyland, Øyvind; Moxnes, John F. (2007)
      In this report an experimental study of the tensile strength of different hard cores of Wolfram Carbide was performed. A bending test was constructed for the study. We show that the tensile strength and strain is smaller ...

    • Wound profiles in soap caused by penetration of high speed spheres 

      Martinussen, Svein Erlend; Moxnes, John F. (2002)
      As a first attempt at identifying a tissue model for use in wound ballistic simulations a study of the wound profiles in soap during deceleration of spherical steel projectiles has been carried out. Experimental data were ...
