  1. 1. From Topology Optimized Concept to Detailed Design via Implicit-based Geometries and Non-linear Finite Element Analysis

    Uppsats för yrkesexamina på avancerad nivå, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Jonatan Gripenberth; [2023]
    Nyckelord :Topologioptimiering; Implicita kroppar; Arbetsflöde; Icke-linjär finita element analys;

    Sammanfattning : A workflow to go from topology optimized concept to a detailed design was created in this thesis. This was done through the use of Implicit-based geometries and Non-linear finite element analysis. LÄS MER

  3. 2. Numerical Assessment of Defects Effect on Boltless Composites Longitudinal Joints

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Mara Santaniello; [2020]
    Nyckelord :;

    Sammanfattning : The work presented in this thesis focuses on the numerical assessment of defects effect on potential boltless design for fuselage panels longitudinal joints, typically identified as High Load Transfer (HLT) configuration. Nowadays, the state-of-art joining technique for primary aircraft composite structures, such as fuselage barrels, is still mechanical fastening. LÄS MER

  4. 3. Cross-comparison of Non-Linear Seismic Assessment Methods for Unreinforced Masonry Structures in Groningen

    Master-uppsats, KTH/Betongbyggnad

    Författare :Viktor Peterson; Zihao Wang; [2020]
    Nyckelord :Non-linear time-history analysis; non-linear pushover analysis; N2-method; equivalent frame model; continuum model; numerical seismic assessment; unreinforced masonry buildings; Olinjär tids-historikanalys; olinjär stjälpningsanalys; N2-metoden; ekvivalent rammodell; kontinuumelement modell; numerisk jordbävningsanalys; oarmerade murverksbyggnader;

    Sammanfattning : A large amount of low-rise unreinforced masonry structures (URM) can be found in Groningen, the Netherlands. More and more induced earthquakes with short duration have been detected in this region due to gas exploitation. LÄS MER

  5. 4. STRUCTURAL ANALYSIS OF TRUSS CONSTRUCTION FOR WIND TURBINE BLADES

    Uppsats för yrkesexamina på grundnivå, Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

    Författare :Björn Weddig; [2016]
    Nyckelord :Wind turbine blade; FRP; Truss system; Instability; Buckling; Non-Linear; Eigenvalue problem; Frequency response analysis; Transient dynamic response; Technology and Engineering;

    Sammanfattning : The usage of wind turbines during the latest years has grown substantially and are becoming an increasingly important source of renewable energy, as many countries are trying to reduce their reliance on fossil fuels. In order to increase the effect of the wind turbines the length of the blades has been increased, which has also led to an increase of the cross-section dimensions. LÄS MER

  7. 5. Design of slender steel members : A comparison between the reduced stress method and the effective width method

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Oskar Skoglund; Daniel Samvin; [2016]
    Nyckelord :Steel structures; finite element method; reduced stress method; effective width method; nonlinear finite element method; Stålkonstruktion; finita element metoden; reducerad spänningsmetoden; effektiva bredd metoden; olinjär finita element analys;

    Sammanfattning : As of now, the most common way in Sweden, to address the issue of local buckling of steelstructures is through the procedure called the effective width method. A less commonprocedure for dealing with local buckling is the reduced stress method. LÄS MER
