  1. 1. Interaction of Cylindrical Penetrators with Ceramic and Electromagnetic Armour

    Författare :Lars Westerling; Kristofer Gamstedt; Bengt Lundberg; Nils G. Ohlson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk fysik med inriktning mot hållfasthetslära; Engineering Science with specialization in Solid Mechanics;

    Sammanfattning : Armoured vehicles have traditionally used steel armour as protection against penetrators such as projectiles and shaped charge jets. The latter produce a thin stretching metal jet, usually of copper, with a tip velocity of about 7-8 km/s. LÄS MER

  3. 2. Impact of Metallic Projectiles on a Ceramic Target Surface : Transition Between Interface Defeat and Penetration

    Författare :René Renström; Bengt Lundberg; Patrik Lundberg; Nils-Gunnar Ohlson; Uppsala universitet; []
    Nyckelord :Engineering physics; Projectile; Cylindrical; Conical; Yield strength; Compressibility; Perfect flow; Self-similar flow; Interface defeat; Dwell; Teknisk fysik; Teknisk fysik med inriktning mot hållfasthetslära; Engineering Science with specialization in Solid Mechanics;

    Sammanfattning : The purpose of this thesis is to gain understanding of the load on flat target surfaces produced by projectile impact. Models are proposed from which upper and lower bounds can be derived for the transition be-tween interface defeat and normal penetration. LÄS MER

  4. 3. Interaction between High-velocity Penetrators and Moving Armour Components

    Författare :Ewa Lidén; Bengt Lundberg; Hevré Couque; Uppsala universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP; Teknisk fysik med inriktning mot hållfasthetslära; Engineering Science with specialization in Solid Mechanics;

    Sammanfattning : This work was aimed at understanding mechanisms of importance for the design of weight-efficient armour against long-rod projectiles (LRP) and shaped charge (SC) warheads. The focus was on how to achieve effective mechanical disturbances on the threat before it hits the target. LÄS MER
