• An experimental study on the deformation and fracture modes of steel projectiles during impact 

      Rakvåg, Knut Gaarder; Børvik, Tore; Westermann, Ida; Hopperstad, Odd Sture (Journal article, 2013)
      Previous investigations of the penetration and perforation of high-strength steel plates struck by hardened steel projectiles have shown that under certain test conditions the projectile may fracture or even fragment upon ...
    • Combined Blast and Fragment Loading on Steel Plates 

      Rakvåg, Knut Gaarder (Doktoravhandlinger ved NTNU, 1503-8181; 2013:361, Doctoral thesis, 2013)
      The thesis describes research related to the combined blast and fragment loading on steel plates. Preliminary experimental work with cased high-explosive charges against steel plates revealed several research topics that ...
    • Fragmentation of Metallic Materials During Impact: Numerical Studies of Fragmentation in the Taylor Test 

      Karlsen, Terje; Kjølseth, Andreas Bjune (Master thesis, 2012)
      This thesis is written in relation to the current research at SIMLab in the field of impact engineering. An overall objective is to establish a general numerical model for predicting and simulating the fragmentation process ...
    • Transient pressure loading of clamped metallic plates with pre-formed holes 

      Rakvåg, Knut Gaarder; Underwood, NJ; Schleyer, GK; Børvik, Tore; Hopperstad, Odd Sture (Journal article; Peer reviewed, 2013)
      The combined effect of blast and impact loading against protective structures is still not fully understood. In this paper, the motivation is to investigate the combined effect of pressure and fragment loading on steel ...
