  1. 1. Baggalútar from Hvalfjörður (Iceland): Enigmatic spheroids of hydrothermally altered basaltic tephra

    University essay from Uppsala universitet/Mineralogi, petrologi och tektonik

    Author : Emmie Djuse; [2022]
    Keywords : Baggalútar; Iceland; basalt; Hvalfjörður; zeolites; volcanic spherulite; spheroids; Baggalútar; Island; basalt; Hvalfjörður; zeoliter; vulkaniska sfäruliter; sfäroider;

    Abstract : Baggalútar are well-rounded spheroids that typically measures 16-18 mm in size and have a brownreddish appearance. They can be found in the Hvalfjörður bay in SW Iceland. READ MORE

  3. 2. Fatigue Crack Growth Analysis in Python algorithm with Finite Element Methods : Numerical Simulation of Fatigue Crack Growth

    University essay from Karlstads universitet

    Author : Hasan Majid; [2022]
    Keywords : ;

    Abstract : The goal of this thesis was to construct and develop a python-based finite element computer program for the evaluation of fatigue crack growth rate in notched metallic rods. The simulation was done by implementing elastic stress theory and linear elastic fracture mechanics techniques. READ MORE

  4. 3. Geomechanical testing of non-hardening grout : for determination of flowability and strength properties

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Axel Barrdahl; [2022]
    Keywords : Non-hardening; Grout; Embankment dam; Repair; Fall cone; Uniaxial Compressive Strength; UCS; Triaxial;

    Abstract : Due to an increasing amount of aging tendencies in Swedish embankment dams, failures such as internal erosion has become a more common problem. Internal erosion is a phenomenon where certain soil material within the embankment dam is removed, often over a longer period of time. READ MORE

  5. 4. Gravity and surface tension-driven waves

    University essay from KTH/Teknisk mekanik

    Author : Albin Hedblom; [2022]
    Keywords : Gravity surface waves; capillary-gravity surface waves; dispersion; experiment;

    Abstract : In this thesis, gravity and surface tension-driven water waves are investigated by designing an experimental setup to track wave patterns using a 300 fps high speed camera. This is done to reproduce the theoretical diagram of the dispersion relation for surface waves in different teaching contexts. Surface waves are dispersive, i.e. READ MORE

  6. 5. Laser Arc Hybrid Welding of Thicker 6000-series Aluminium Alloy : Laser-MIG butt welding of 8 mm 6082-t6

    University essay from KTH/Industriell produktion

    Author : Björn Lindeberg Nilsson; [2022]
    Keywords : ;

    Abstract : Laser arc hybrid welding presents many benefits but has many parameters that must be optimised for it to work. It becomes even more challenging when welding thicker aluminium with the process. Welding of thicker aluminium alloys involves a lot of different challenges, on itself. READ MORE
