  1. 1. Styrd Fragmentering i Metalliska Stridsdelar : Teknikutveckling av fragmenterande stridsdelar

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :William Persson; Lukas Rehnberg; [2022]
    Nyckelord :Smoothed Particle Hydrodynamics; CAD; Electron Beam Melting; Stridsdel; Additiv tillverkning; AM; Teknikutveckling; Fragment; Granat; Simulering;

    Sammanfattning : Fragmenterande stridsdelar har funnits länge och idag finns tre huvudsakliga metoder för att uppnå fragmentering i en stridsdel. Metoden styrd fragmentering som undersöks i arbetet fungerar generellt sett bra men saknar önskad kontrollförmåga. LÄS MER

  2. 2. Simulations of experimental crack development in ceramic material with notched specimen

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Clas Dahlin; [2022]
    Nyckelord :Solid Mechanics; Fracture mechanics; Ceramics; Dynamics; Ballistics; Hållfasthetslära; Brottmekanik; Keramer; Dynamik; Ballistik;

    Sammanfattning : Low-density armour often uses ceramic materials, as their high compressive strength and relatively low weight make the material ideal for moving in the field. The ballistic protection works by redirecting the plastic flow of the projectile radially, which reduces penetration. LÄS MER

  3. 3. Asymmetries in shaped charges

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Gustav Boman; [2021]
    Nyckelord :;

    Sammanfattning : This thesis concerns the effects of a select few asymmetries on a jet formingshaped charge. A Shaped charge(SC) is a formed explosive with metal liner thatcollapses under the detonation. The resulting shock­compression results in a jetof metal being shot forward in up 10km/s. LÄS MER

  4. 4. Velocity Compensation in Shaped Charges

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Anmol Bhullar; [2021]
    Nyckelord :;

    Sammanfattning : Shaped charges (SC) have been used as a means of explosives in military andcivilian use for decades. Thus, there is a substantial amount of research behindthis area. However, as this is a sensitive subject much of this research is notpublicly available. LÄS MER

  5. 5. Shaped Charge Design : Construction of a Miniaturized Shaped Charge

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Andreas Gustafsson; [2021]
    Nyckelord :Shaped Charge; Explosively Formed Penetrator; Smoothed Particle Hydrodynamics; Electron Beam Welding;

    Sammanfattning : The shaped charges on the market today ranges from about 20 to 200 mm in diameter but there is a need of smaller sizes for example in applications where a small projectile with a high speed is needed or to equip or take out drones with. The objective of this thesis work was to develop a miniaturized shaped charge with dimensions smaller than those available today and preferably with a diameter down to 10 mm. LÄS MER
