  1. 6. Finite element methods applied to boundary value problems derived from the deflection curve of a beam under the action of a point and a uniformly distributed load

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för matematik (MA)

    Författare :Silhady Tshitende Luboya; [2018]
    Nyckelord :;

    Sammanfattning : In this thesis, we analyze a roller - pinned supported beam of length L subjected to a point load at a distance `1 and a uniformly distributed load over the entire span of the beam. The aim of this study is to determine the slope and the vertical deflection curve of the beam. LÄS MER

  3. 7. Domain Decomposition Methods for Finite Periodic Structures in Electromagnetics

    Uppsats för yrkesexamina på avancerad nivå, KTH/Elektroteknisk teori och konstruktion

    Författare :Gustav Casselbrant; [2012]
    Nyckelord :;

    Sammanfattning : Long computational times persist on being a limiting factor when designing complex electromagnetic structures. Even though computers get more and more powerful, the most efficient improvement for reducing the necessary time when solving a numerical problem is to change or optimise the used numerical method.

  4. 8. Frequency Response Analysis using Component Mode Synthesis

    Master-uppsats, Institutionen för matematik och matematisk statistik

    Författare :Tor Troeng; [2010]
    Nyckelord :Component Mode Syntesis; model reduction; frequency response analysis;

    Sammanfattning : Solutions to physical problems described by Differential Equationson complex domains are in except for special cases almost impossibleto find. This turns our interest toward numerical approaches. Sincethe size of the numerical models tends to be very large when handlingcomplex problems, the area of model reduction is always a hot topic.

  5. 9. Analysis of Three-Dimensional Cracks in Submodels

    Magister-uppsats, Institutionen för ekonomisk och industriell utveckling

    Författare :David Karlsson; [2007]
    Nyckelord :Crack; fracture; stress intensity factor; submodel; three-dimensional;

    Sammanfattning : A common technique to evaluate load paths in complex structures is to perform FE-calculations with relative large elements. This procedure gives no information regarding stress concentrations at e.g. holes or radius but this phenomenon can later on be investigated in details with local individual submodels. LÄS MER
