  1. 21. Efficient Quadrature Settings for Elliptic PDE’s using a Coupled FEM and BEM Solver in COMSOL Multiphysics

    University essay from KTH/Numerisk analys, NA

    Author : Gustav Friberg; [2014]
    Keywords : ;

    Abstract : By using singular integral kernels based on the fundamental solution, a partial differential equation (PDE) can be rewritten as a boundary integral defined at the boundary of a domain. This requires a linear differential operator with coefficients that are isotropic and homogeneous in space. READ MORE

  3. 22. Simplification of 3d cooled turbine blade models for efficient dynamic analyses

    University essay from KTH/Kraft- och värmeteknologi

    Author : Arokia Arokia Lourdu Marshall; [2013]
    Keywords : SGT-750; Cooled turbine blades;

    Abstract : In gas turbines, the temperature behind the combustors is the highest, meaning that the blades in the first stage of the turbine require cooling air. This makes the structural blade model very detailed due to the presence of the cooling pattern. READ MORE

  4. 23. Numerical Simulation of the Curing Process of Fiber Reinforced Polymer Composites

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Amir Haji Hosseini; [2013]
    Keywords : Cure Kinetics; Finite Element Method; Unstructured Mesh Generation; MATLAB;

    Abstract : The curing process of Fiber reinforced polymer rebars using a two phase curing process is investigated in this work. These rebars are developed as an alternative reinforcing material in reinforced concrete. The chemical resistance and high specific strength and stiffness of these rebars make them an important subject for research .. READ MORE

  5. 24. Simulating Bird Strike on Aircraft Composite Wing Leading Edge.

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Max Ericsson; [2012]
    Keywords : ;

    Abstract : In this master thesis project the possibility to model the response of a wing when subjected to bird strike using finite elements is analyzed. Since this transient event lasts only a few milliseconds the used solution method is explicit time integration. The wing is manufactured using carbon fiber laminate. READ MORE

  6. 25. Method Evaluation of Global-Local Finite Element Analysis

    University essay from Hållfasthetslära; Tekniska högskolan

    Author : Gabriella Ahlbert; [2012]
    Keywords : finite element method; gloabl-local; sub-modeling; superelement;

    Abstract : When doing finite element analysis upon the structure of Saab’s aeroplanes a coarse global model of mainly shell elements is used to determine the load distribution for sizing the structure. At some parts of the aeroplane it is however desirable to implement a more detailed analysis. READ MORE
