  1. 21. Repeatability of Additive Manufactured Parts

    University essay from KTH/Materialvetenskap

    Author : Sofia Tollander; Mona Kouach; [2017]
    Keywords : Additive Manufacturing; 3D-printing; Repeatability; Vibration Test; Aluminium Alloy; Additiv tillverkning; 3D-printing; Repeterbarhet; Vibrationstest; Aluminiumlegering;

    Abstract : Saab Surveillance in Järfä̈lla constructs complex products, such as radars and electronic support measures. Saab sees an advantage in manufacturing details with additive manufacturing as it enables a high level of complexity. Additive manufacturing is relatively new in the industry and consequently there are uncertainties regarding the process. READ MORE

  3. 22. A Cut Finite Element Method for Partial Differential Equations on Evolving Surfaces

    University essay from KTH/Numerisk analys, NA

    Author : Johan Wärnegård; [2016]
    Keywords : ;

    Abstract : This thesis deals with cut finite element methods (CutFEM) for solving partial differential equations (PDEs) on evolving interfaces. Such PDEs arise for example in the study of insoluble surfactants in multiphase flow. In CutFEM, the interface is embedded in a larger mesh which need not respect the geometry of the interface.

  4. 23. Non-Linear Assessment of a Concrete Bridge Slab Loaded to Failure

    University essay from KTH/Betongbyggnad

    Author : Eriksson Isabell; Niklas Karlsson; [2016]
    Keywords : concrete; linear shear; punching shear; non-linear finite element analysis; Eurocode; Model Code; ATENA 3D; betong; skjuvning; genomstansning; icke-linjär finit-elementanalys; Eurocode; Model Code; ATENA 3D;

    Abstract : This thesis covers an investigation regarding the failure in the bridge slab of Gruvvägsbron, which was the result of the full scale test that the bridge was subjected to prior to demolition. Using the non-linear finite element software ATENA 3D, a model of the bridge was assembled, with the purpose to attempt to reenact the test procedure and realistically capture the failure load and behaviour.

  5. 24. Numerical analyses of concrete buttress dams to design dam monitoring

    University essay from KTH/Betongbyggnad

    Author : Daniel Svensen; [2016]
    Keywords : Concrete; buttress dams; thermal effects; finite element analysis; instrumentation; alarm values; alert values; Betong; lamelldammar; termiska effekter; finit element analys; intstrumentering; larmvärden;

    Abstract : Old concrete buttress dams are sensitive to cracking if exposed to large temperature variations. The cracks can make dams sensitive to failure, depending on the size and location of the cracks. These problems can be overcome by lowering the temperature variations and stabilizing the dams.

  6. 25. Behavior of Swedish Concrete Buttress Dams at Sesmic Loading

    University essay from KTH/Betongbyggnad

    Author : Erik Forsgren; Isak Berneheim; [2016]
    Keywords : seismic; Swedish earthquake; buttress dam; concrete; finite element analysis; seismik; jordbävning; lamelldamm; betong; finit element analys;

    Abstract : The aim of the thesis is to study the response of Swedish buttress dams if they are subjected to an earthquake of relevant magnitude to Sweden. Swedish dams are evaluated for an extensive amount of load cases, but not for earthquake loading. Therefore, it is not known how the Swedish buttress dams would respond during such loading. READ MORE
