  1. 16. Structure–Acoustic Interaction Between Vehicle Floor Panels and Carpets – Numerical Simulations and Measurements

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

    Författare :Aya Karim; Jesper Brindhag; [2021]
    Nyckelord :Structure-acoustic; Acoustic; Dynamic; Floor panels; Interior carpets; NVH; FEM; Finite element; PEM; Porous elastic; Noise radiation; Interior-noise; Vehicles; Vibration; Structure-borne noise; Technology and Engineering;

    Sammanfattning : An attribute that is highly valued amongst vehicle customers is low interior-noise levels when a vehicle is in use. Much of the interior-noise is believed to stem from the vibrations of floor panels in vehicles. LÄS MER

  3. 17. Crack growth based FEM with embedded discontinuities

    Master-uppsats, KTH/Hållfasthetslära

    Författare :David Lindblom; [2021]
    Nyckelord :PUFEM; Fracture Mechanics; J2-plasticity; FEAP; Strong discontinuity; Variational formulation; XFEM; PUFEM; Brottmekanik; J2-plasticitet; FEAP; Diskontinuitet; variationskalkyl;

    Sammanfattning : In recent years there have been a major developments in the computational mechanics community when it comes to modelling of fracture mechanics. There are now several well established numerical methods that are implemented in commercial programs such as: Phase Field Modelling, Enhanced Assumed Strain (EAS), Smeared Crack Methods, Extended Finite Element Method (XFEM) and Partition of Unity Finite Element Method (PUFEM).

  4. 18. Modelling masonry spires : An investigation

    Master-uppsats, KTH/Betongbyggnad

    Författare :Dennis Lillemo; [2021]
    Nyckelord :Abaqus; Concrete damage plasticity; Finite element method; Limit analysis; Macro-modelling; Masonry; Masonry spire; Nonlinear material; Salisbury Cathedral; Abaqus; Concrete damage plasticity; Finita elementmetoden; Gränsanalys; Makromodellering; Murverk; Murad tornspira; Icke-linjärt material; Katedralen i Salisbury;

    Sammanfattning : Masonry spires are a typical part of church architecture. Since it is rare that masonry is used as a load-bearing material in the western world today, it is important to maintain and increase the knowledge of modelling masonry structures both from a maintenance point of view and to build new masonry structures.

  5. 19. Arm Injury Prediction with THUMS SAFER: Improvements of the THUMS SAFER upper extremity

    Master-uppsats, KTH/Hållfasthetslära; KTH/Lättkonstruktioner

    Författare :Mariam Bayat; Nichakarn Pongpairote; [2020]
    Nyckelord :Biomechanics; upper extremity; arm; validation; Total HUman Model for Saftey THUMS ; Finite Element Modelling FEM ; Biomekanik; övre extremitet; arm; validering; Total HUman Model for Saftey THUMS ; Finite Element Modellering FEM ;

    Sammanfattning : Globally, approximately 1.2 million people die each year due to traffic accidents. Upper extremity injuries account for 18% to 25% of all car accident injuries. In order to be able to analyze these crash-related injuries, Human body models(HBMs) are used as a complement to FE simulations. LÄS MER

  7. 20. Load modelling of a mobile miner

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Rafail-Nikolaos Dimitriou; [2020]
    Nyckelord :;

    Sammanfattning : In the mining industry, finite element analysis (FEA) and experimental tests are essential for the verification of mechanical properties and for performing parametric studies. Such practices require lots of resources and, sometimes, long computational time. LÄS MER
