  1. 1. Structural responses due to underwater detonations : Validation of explosion modelling methods using LS-DYNA

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Gustav Blomgren; Ebba Carlsson; [2023]
    Nyckelord :Underwater explosion; UNDEX; detonation; fluid structure interaction; FSI; SSA; S-ALE; shock-wave; explosive; PETN; explosive modelling; Sub-Sea Analysis; Structured ALE; Arbitrary Lagrangian Euler; Multi Material Arbitrary Lagrangian Euler; MMALE; LS-DYNA;

    Sammanfattning : Modelling the full event of an underwater explosion (UNDEX) is complex and requires advanced modelling methods in order to achieve accurate responses. The process of an UNDEX includes a series of events that has to be considered. LÄS MER

  3. 2. Design Development of a Hydrostat : Construction of a hydrostat used in an underwater SAI-unit

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

    Författare :Abbas Mohammadi; [2021]
    Nyckelord :Hydrostat; Saab Dynamics; Design; UNNDEX; Pressure;

    Sammanfattning : Working with and providing different military and industrial solutions, SBD’s (Saab Dynamic) work also involve underwater equipment and underwater weapon (UW) systems. Nowadays, there are a number of standards that should be followed to make weapon systems safe to use, transport and handle. LÄS MER

  4. 3. Structural Analysis of Underwater Detonations

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Edvin Sjöstrand; [2021]
    Nyckelord :UNDEX; LS-Dyna; MMALE;

    Sammanfattning : The knowledge how an object withstand an underwater detonation is critical within the defense industry. This is mostly done today with physicals test which are both time consuming and connected with high costs. LÄS MER
