  1. 1. Development of a DEM-FEM framework for infrastructure simulations

    Master-uppsats, Göteborgs universitet / Institutionen för fysik

    Författare :Anita Ullrich; [2022-09-20]
    Nyckelord :;

    Sammanfattning : This thesis presents a coupling algorithm of the discrete element method (DEM) and finite element method (FEM). The algorithm formulates an explicit coupling of transient simulations of particle systems interacting with elastic bodies. LÄS MER

  3. 2. Modelling and simulation of vibratory driven sheet piles - Development of a stop criterion

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

    Författare :Johannes Jonsson; Anton Andersson; [2021]
    Nyckelord :Vibratory driving; sheet pile; Technology and Engineering;

    Sammanfattning : During excavations, steel sheet piles are often installed through vibratory driving, to establish a retaining wall that resists soil instability and ground water leakage. The method of vibratory driving is that the sheet pile is driven into the soil with a vertical vibratory motion. This is especially effective in soft soils. LÄS MER

  4. 3. Numerical simulations of shear reinforced concrete beams subjected to blast loads

    Master-uppsats, KTH/Betongbyggnad

    Författare :Anton Frank; Andreas Fristedt; [2021]
    Nyckelord :Numerical simulations; shear reinforcement; blast loads; dynamic shear failure; Numeriska simuleringar; tvärkraftsarmering; luftstötvåg; dynamiskt skjuvbrott;

    Sammanfattning : Historical accidents and experimental investigations have made apparent that blast loaded concrete members are prone to fail in brittle shear rather than a ductile flexure mode. Air blasts from accidental detonations or explosives may cause severe damage to buildings and infrastructure and it is of great importance that load carrying members can withstand the impulse that arise to avoid progressive collapses.

  5. 4. Dynamic Finite Element Modelling of a Fall on the Hip

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Nils Nyberg; [2021]
    Nyckelord :Hip Fracture; Finite Element Modeling; Finite Element; Femur Fracture; Sideways Fall; Technology and Engineering;

    Sammanfattning : Assessing the risk of future femur fracture is an important step in preventing this serious and common injury. The current methods to predict the fracture risk are typically based on bone mineral density measurement, used as a surrogate for femoral strength. LÄS MER

  7. 5. Improving comfort simulations of sleeping mattresses for IKEA

    Master-uppsats, Lunds universitet/Innovation

    Författare :Joel Elinder; [2020]
    Nyckelord :LS-Dyna; explicit finite element simulations; compressive testing; human soft tissue material models; mass scaling; hyperelastic material model validation; material validation; explicit timestep; Technology and Engineering;

    Sammanfattning : It is beneficial for a furniture company like IKEA to objectively and accurately evaluate what makes a mattress comfortable. But what defines comfort? IKEA currently investigates mattress comfort through extensive real-life user testing. Through which, six parameters of comfort have been identified. LÄS MER
