  1. 21. FEM analysis of existing buildings during renovation

    University essay from KTH/Hållfasthetslära

    Author : Agnes Nyberg; [2023]
    Keywords : Sturegallerian; Räumlich Finite Element Method; Euro code; Masonry; Steel amplifier; Sturegallerian; Räumlich Finita Element Metod; Eurokoder; Murverk; Stål förstärkning;

    Abstract : In this masters thesis the aim was to investigate a part of Sturegallerian in Stockholm to be reconstructed. The reconstruction did implicate that openings were to be established in an already existing masonry wall. READ MORE

  3. 22. Thermal Analysis of Tap- Changers

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Daniel Lundberg; [2023]
    Keywords : Thermal analysis; COMSOL; tap-changers; heat transfer;

    Abstract : This thesis provides a way of mapping the temperature development of the tap-changer oil for some different standardized loading cases. The project was in collaboration with Hitachi Energy for one of their production cites situated in Ludvika, Sweden. The software used for the simulation environment was COMSOL 6.1 which is a finite element solver. READ MORE

  4. 23. Finite-Element Analysis of Cryogenic Pressure Vessels Under Blast Loading

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Casper Liavåg; [2023]
    Keywords : Cryogenic Pressure Vessel; Blast; Blast Loading; Pressure Vessel; Launch Infrastructure;

    Abstract : The behavior of cryogenic double-walled pressure vessels, such as thoseused in space launch vehicle infrastructure, under blast loading is a somewhatunderstudied topic. This is of interest due its implications on, among otherthings, launch site design and safety in the event of a launch vehicle failure. READ MORE

  5. 24. Evaluation of load distribution on ballasted reinforced concrete railway trough bridges

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Alex Eriksson; [2023]
    Keywords : Concrete; numerical analysis; trough bridge; railway bridge; finite element model; discrete element method; Betong; numeriskanalys; trågbro; tågbro; finita elementmetoden; diskreta elementmetoden;

    Abstract : A significant portion of the reinforced concrete railway bridges in Sweden are reaching their designed lifespan and are scheduled to be demolished and replaced in the upcoming years. To limit the econom-icand environmental impact related to the replacement of existing railway infrastructure, a comprehen-siveevaluation of their capacity is required with the aim of extending its lifespan.

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

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Gustav Blomgren; Ebba Carlsson; [2023]
    Keywords : 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;

    Abstract : 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. READ MORE
