  1. 1. Numerical simulations of Carbon Fiber ReinforcedPolymers under dynamic loading

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Edoardo Taddei; [2017]
    Nyckelord :;

    Sammanfattning : The ability to withstand dynamic loading represents an important design criteria for crucial applications such as those adopted in the automotive and aerospace industries. Numerical simulations can lead to a reduction of time and costs for designing composite structures by replacing testing campaigns that are performed in order to assess whether the design requirements of the structure are met.

  3. 2. Simulation of cantilever construction of cable-stayed bridges taking into account time dependent phenomena

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Josep Farre Checa; [2017]
    Nyckelord :Cable-stayed bridges; Cantilever method; Objective Service Stage; CIP concrete; Creep; Dischinger hypothesis; Forward analysis.;

    Sammanfattning : In the design of cable-stayed bridges, the construction analysis is very important since the worst stresses are usually reached during the construction process. In addition, if the bridge is made of concrete, the effects of time dependent phenomena have great importance. LÄS MER

  4. 3. Patch loading resistance of welded I-beams : with respect to misaligned web stiffeners

    Master-uppsats, KTH/Stålbyggnad

    Författare :John-Alexander Boutzas; Dafina Zeka; [2016]
    Nyckelord :Patch loading; Stiffeners; I-beam; Plated steel structures; Abaqus; Simply supported beam;

    Sammanfattning : When a concentrated load is introduced perpendicular to the flanges of a steel beam, this condition is referred to as Patch loading (Gozzi, 2007). This occurrence is common in many steel structures, for example at supports or during launching of bridges. LÄS MER

  5. 4. 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

  7. 5. Thin metal patch to FRP propeller: Experimental testing of bonding systems

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Mårten Kreiss Amberg; [2015]
    Nyckelord :;

    Sammanfattning : To enable the use of carbon fibre reinforced polymer (CFRP) propellers for merchant vessels, the problem of cavitation must be solved. The matrix of the FRP is generally brittle and more sensitive to cavitation erosion than the more conventional metal propeller blades. Nakashima Propeller Co. LÄS MER
