  1. 1. FE-Modelling of Composite Girder tests

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Holger Berggren; Bergstedt Ola; [2024]
    Nyckelord :shear connector; post-installed; coiled spring pins; composite girder; partial composite action; finite element method;

    Sammanfattning : Many of the existing steel-concrete bridges may need to be strengthened, as heavier vehicles areallowed on the Swedish roads. These bridges could possibly be strengthened by post-installingshear connectors. The shear connectors may enhance the load-bearing capacity through a higherdegree of composite action between the steel and concrete interface. LÄS MER

  3. 2. Interaction for flexural column buckling : Analytical procedures compared with FE-simulations

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Noah Norberg; [2023]
    Nyckelord :;

    Sammanfattning : This master's thesis presents a study on the stability of steel structures under flexural bucklingconstraints. The study focuses on the interaction and behaviour of flexural buckling formulas in SSEN-1993-1-1 and Swedish BSK and the performance of actual structural members subjected to suchconstraints.

  4. 3. A theoretical framework for interpretation and prediction of magneto-optical measurements

    Kandidat-uppsats, Uppsala universitet/Materialteori

    Författare :Viktor Frilén; [2023]
    Nyckelord :moke; tmoke; lmoke; pmoke; magneto-optical effects; layered media; dielectric function; maxwells equations; dielectric tensor; linear respons; magnetism; light induced transistions; DFT; SO;

    Sammanfattning : The interplay of experiments and theory is essential to deepen our understanding of magnetization dynamics. This thesis aims to serve as a bridge between these two aspects by establishing a mathematical framework that enables the computation of optical observable quantities based on theoretical models.

  5. 4. Solar Photovoltaic Fire Risks : FE-analysis of fire exposed solar photovoltaic systems and comparison of current legislation and recommendations from different countries

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Elin Bergroth; Greta Torstensson; [2023]
    Nyckelord :Solar Photovoltaic; National Guidelines; Fire Department; FE-analysis; TASEF; Solceller; Nationella Riktlinjer; Räddningstjänst; FE-analys; TASEF;

    Sammanfattning : The global use of energy increases every day and to meet the growing demand, energy sources are constantly being developed to become more efficient and reliable. During the last decade, the global solar photovoltaics (PV) capacity has increased every year and in 2017, solar PV was the global leading power source of renewable energy. LÄS MER

  7. 5. Bedömning av prediktiv förmåga för Finita Elementberäkningar med optisk töjningsmätning (DIC)

    Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Albin Zetterqvist; Linus Hjelm; [2023]
    Nyckelord :Digital image correlation; Finite element; Predictive capability; Model calibration; FEM; DIC; Modellkalibrering;

    Sammanfattning : The goal of this thesis is to improve the predictive capability of Finite element (FE) by gathering data from experimental test and implement the characteristics into the material model that is used. FE is a commonly used method to predict the mechanical behavior of materials and components during applied forces. LÄS MER
