  1. 1. Embedment Behavior of Steel Dowel in Timber Loaded Perpendicular to the Grain : Influence of Assembly History in Combination with Moisture Change and Cyclic Loading

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Mojtaba Khalili; [2023]
    Keywords : Embedment strength; elastic and plastic embedment stiffness; moisture content; swelling and shrinkage; steel dowel; assembly history; cyclic loading;

    Abstract : The embedment behavior of dowels in timber structures, as an essential parameter in the design of connections, is the subject of this thesis. There are numerous advantages using timber structures, including sustainability, energy efficiency, and aesthetic appeal. READ MORE

  3. 2. Life Cycle Assessment of Borehole Thermal Energy Storage

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Saga Karlsson; [2022]
    Keywords : ;

    Abstract : Borehole thermal energy storage (BTES) is a technology used to store energy between seasons. It could therefore be a solution to the seasonal mismatch between the use and production of (renewable) energy, which can be used to increase energy efficiency and reduce greenhouse gas emissions.

  4. 3. Identifying Important Features to Minimize Hole Deviation in Percussive Drilling

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Ketan Dhananjay Deshpande; [2021]
    Keywords : Bending; Buckled profile; Drilling; Hole deviation; Mathematical model; Böjning; Buckled profil; Borrning; Hålavvikelse; Matematisk modell;

    Abstract : Hole deviation is one of the most significant problems in drilling applications. Deviated holes result in inefficient blasting and have severe economic impacts due to increased equipment consumption. Conversely, straighter holes help in increasing production scales and reduce operational costs. READ MORE

  5. 4. A comparative study on hole quality criteria on CFRP drilling

    University essay from Lunds universitet/Industriell Produktion

    Author : Jerome Paul Raenius Jeevanandham; Sakthivel Balaji; [2021]
    Keywords : CFRP; Composites; Hole quality; Delamination; Uncut fibers; Technology and Engineering;

    Abstract : Drilling is an essential hole-making operation in the modern industrial world. Drilling operation is comparatively challenging in composites when compared to metals. Composites are heterogeneous and possess a high strength-to-weight ratio which makes it a challenge in composite drilling. READ MORE

  6. 5. Cooling Strategy Influence on Temperature in ETD Center

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Oskar Edinger; [2021]
    Keywords : Machining; Drilling; Exchangeable tip drill; 316L Stainless steel; Thermocouple; IR Thermography; Skärande bearbetning; Borrning; Löstoppsborr; 316L Rostfritt stål; Termoelement; IR Termografi;

    Abstract : Striving for increased productivity while maintaining hole quality and high process robustness when drilling requires knowledge about the working principles of heat generation, mechanics and a proper cutting fluid that aids in cooling, lubricating and evacuating chips from the cutting zone. If the heat generated in the tool-workpiece and tool-chip interfaces does not exit the cutting zone adequately through the chips, the workpiece material or the redistribution of coolant the hole quality can be impacted negatively and breakdowns may occur which reduces overall productivity.
