  1. 1. 4-Point Bending of Composite Laminates for FEM/FEA Validation

    Magister-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Pierce Cashin; [2023]
    Nyckelord :composites; 4-point bending; fiberglass; sandwich panel;

    Sammanfattning : When designing structures and vehicles using composite materials, engineers need access to critical information regarding the composite materials in question. This information describes the strength, stiffness, failure mode, and other variables that can be used to properly determine how a structure will perform while undergoing various loads and effects.

  3. 2. Catenary action to prevent progressive collapse in multistorey timber buildings : An experimental study of tube joints

    Master-uppsats, Luleå tekniska universitet/Träteknik; Luleå tekniska universitet/Institutionen för tillämpad fysik, maskin- och materialteknik

    Författare :Sivert Knutsen; [2023]
    Nyckelord :wood; engineering; construction; massive timber; tube joints; Progressive collapse;

    Sammanfattning : In the modern building industry wood as a building material has been looked on as one of the solutions to lower the environmentally impact of the building industry. Building types that normally have been reserved for concrete and steel are today being built with wood as main load bearing component. LÄS MER

  4. 3. A parametric study of the static and dynamic performance of timber arch footbridges with different hanger configurations

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :ALEJANDRO GARCÍA GARCÍA; [2022]
    Nyckelord :Arch bridges; footbridge dynamics; critical load; bridge typology; parametric study;

    Sammanfattning : The influence of the hanger configuration in the arch and deck bending moments under asymmetric loads is widely used nowadays for improved designs of arch bridges. In this work, by means of a parametric study, those hanger configurations that most efficiently increase both the natural frequencies and buckling factors are identified, simultaneously evaluating the dynamic and static performance of timber arch footbridges.

  5. 4. Numerical study of a vibroacoustic wave trap for e-vehicles

    Master-uppsats, KTH/Teknisk akustik

    Författare :Antoine Curien; [2022]
    Nyckelord :wheel vibrations; passive vibration control; multiple tuned mass damper; bending mode; numerical optimisation; damping; resonance; robustness; reduction methods; Hjulvibrationer; passiv vibrationsreglering; multi tuned mass damper; böjningsläge; numerisk optimering; dämpning; resonans; robusthet; modale reduktionsmetoder;

    Sammanfattning : The transition from internal combustion engine to battery electric cars is accompanied by a shift on the NVH issues damaging the passenger comfort. The rolling noise generated by the wheels and tyres is in particular characterized by an increasing attention from OEMs and car manufacturers. LÄS MER

  7. 5. Simulations of experimental crack development in ceramic material with notched specimen

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Clas Dahlin; [2022]
    Nyckelord :Solid Mechanics; Fracture mechanics; Ceramics; Dynamics; Ballistics; Hållfasthetslära; Brottmekanik; Keramer; Dynamik; Ballistik;

    Sammanfattning : Low-density armour often uses ceramic materials, as their high compressive strength and relatively low weight make the material ideal for moving in the field. The ballistic protection works by redirecting the plastic flow of the projectile radially, which reduces penetration. LÄS MER
