  1. 1. 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

  3. 2. Interface Defeat and Penetration: Two Modes of Interaction between Metallic Projectiles and Ceramic Targets

    Författare :Patrik Lundberg; Bengt Lundberg; Charles E. Anderson Jr.; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; projectile; target; impact; interface defeat; penetration; tungsten; ceramic; replica scaling; Teknisk fysik; Engineering physics; Teknisk fysik;

    Sammanfattning : Ceramics constitute an important group of low-density armour materials. Their high intrinsic strength makes it possible to design ceramic armour systems capable of defeating projectiles directly on the ceramic surface. LÄS MER

  5. 4. Interaction of Cylindrical Penetrators with Ceramic and Electromagnetic Armour

    Författare :Lars Westerling; Kristofer Gamstedt; Bengt Lundberg; Nils G. Ohlson; Uppsala universitet; []

    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
