  1. 16. Evaluation of cracks in corrugated board, Evaluating cracks using Finite Element Method and J-integral

    University essay from KTH/Hållfasthetslära

    Author : Ming-Yang Li; [2021]
    Keywords : corrugated board; corrugated box; finite element method; fracture mechanics; mechanical properties; wellpapp; finita elementmetoden; frakturmekanik; mekaniska egenskaper;

    Abstract : This report investigates whether a FEM model can be used to assess the risk of crack growth in corrugated board. A set of box geometries with cracks at different locations were loaded and then compared using the evaluated J-integral within the FEM software. READ MORE

  3. 17. Simulated cerebrospinal fluid motion due to pulsatile arterial flow : Master Thesis Project

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jesper Hägglund; [2021]
    Keywords : Computational fluid dynamics; Fluid structure interaction; Pulsatile flow;

    Abstract : All organs, including the brain, need a pathway to remove neurotoxic extracellular proteins. In the brain this is called the glymphatic system. The glymphatic system works by exchanging proteins from interstitial fluids to cerebrospinal fluids. The extracellular proteins are then removed through the cerebrospinal fluid drains. READ MORE

  4. 18. Dynamic Blast Load Analysis using RFEM : Software evaluation

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Oskar Dädeby; [2021]
    Keywords : Blast load; Dynamic; RFEM; time history; experiment; time step;

    Abstract : The purpose of this Master thesis is to evaluate the RFEM software and determine if it could be used for dynamic analyses using blast loads from explosions. Determining the blast resistance for a structure is a growing market and would therefore be beneficial for Sweco Eskilstuna if RFEM could be used for this type of work. READ MORE

  5. 19. Structure–Acoustic Interaction Between Vehicle Floor Panels and Carpets – Numerical Simulations and Measurements

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Aya Karim; Jesper Brindhag; [2021]
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 20. Micro-architectured materials for noise and vibration control in high voltage products – design and modelling

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Alec Chamberlain; [2021]
    Keywords : Microarchitectured; lattice; elasticity; viscoelasticity; computational; homogenization;

    Abstract : Many Hitachi ABB Power Grids (HAPG) products vibrate and emit noise, but legal limitations of these parameters fuel the development of energy absorption methods used on products. Methods such as Constrained Layer Damping (CLD). READ MORE
