  1. 11. The effect of vessel holes on fracture behaviour in the femoral neck of the human femur

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Sofia Rokkones; Karin Odin; [2020]
    Keywords : image analysis; femur; FE model; biomechanics; CT image; Technology and Engineering;

    Abstract : Hip fractures are widely spread in today's society and affect a person's quality of life. Osteoporosis is a bone disease that results in more fragile bones and an increased risk of bone fractures, including hip fractures. A method proposed for assessing the fracture risk is finite element (FE) models of the femur. READ MORE

  3. 12. FE-analysis of roller creasing of corrugated board

    University essay from KTH/Hållfasthetslära

    Author : Isak Hampel Klang; [2020]
    Keywords : ;

    Abstract : Creasing is often performed on paperboard to lower the bending stiffness in a region, making the paperboard easier to fold. Packsize AB uses rolls to crease corrugated paperboard. When using rolls for creasing double-walled corrugated paperboard in the machine direction, fracture occasionally occur on the top liner. READ MORE

  4. 13. Numerical and experimental analysis of adhesively bonded T-joints : Using a bi-material interface and cohesive zone modelling

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Andreas Andersson Lassila; Marcus Folcke; [2018]
    Keywords : adhesive; cohesive zone modelling; Finite Element Method; mixed-mode; T-joint; fracture; experiment; cohesive laws; Bi-material Interface;

    Abstract : With increasing climate change the automotive industry is facing increasing demands regarding emissions and environmental impact. To lower emissions and environmental impact the automotive industry strives to increase the efficiency of vehicles by for example reducing the weight. READ MORE

  5. 14. In-situ Reduction by Incorporating H2 Filled Hollow Glass Microspheres in PM HIP Capsules

    University essay from KTH/Materialvetenskap

    Author : Emil Strand; [2018]
    Keywords : Hot isostatic pressing; hollow glass microspheres; powder metallurgy; oxide reduction; surface oxides; hydrogen;

    Abstract : For many metal components the presence of hard, non-metallic inclusions such as oxides lowers the impact toughness by acting as fracture initiation points and easing crack propagation. In components produced by powder metallurgy hot isostatic pressing (PM HIP), oxides often form a continuous network of small, spherical inclusions after consolidation at the prior particle boundaries (PPB).

  6. 15. Investigating the decrease ofgroundwater levels and the effect of fracture zone on recovery time: A case study of decrease in groundwater levels in a tunnel construction site in Vinsta, Stockholm

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Evgenia Kassiou; [2017]
    Keywords : Groundwater; spatial analysis; Modified Double Mass Statistical Analysis; 3D model; COMSOL Multiphysics; fracture zone; recovery time; soil layer;

    Abstract : Groundwater is one of the main natural resources worldwide. Groundwater exists in aquifers below the earth surface and provides quantities of water for various purposes such as supply to households and businesses, public supply, drinking water supply, irrigation and agriculture. Sweden is also highly dependent on groundwater. READ MORE
