  1. 1. Compaction Simulation for Prepreg-AutoclaveManufacturing : Improvements and Simplifications of Two Compaction Simulation Methodologies

    University essay from KTH/Lättkonstruktioner

    Author : Charlotte Chan; [2019]
    Keywords : ;

    Abstract : In a competitive market such as the aerospace industry, the use of manufacturing process simulation is vital to decrease time and cost of tooling and process development. In the autoclave process, to obtain an uniform part with no void, it is crucial to understand the compaction phenomenon. READ MORE

  2. 2. Friction and wear study of lean powder metallurgy steel in a lubricated sliding contact

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Caroline Lejonklo; [2019]
    Keywords : Lean steel; Powder metallurgy PM ; Powder metallurgy steel PM steel ; Friction; Wear; Sliding contact; Lubricated; Porosity; Tribology; Adhesive wear; Abrasive wear; Gear; Gear tooth; Particles; Polyalphaolefin 8 PAO 8 ; Contact pressure; Density; Light optical microscopy LOM ; Scanning electron microscopy SEM ; Energy-dispersive X-ray spectroscopy EDS ; Vertical svanning interferometry VSI ; Pin on disc; Pin-on-disc;

    Abstract : A fairly new technology used to produce metallic components is powder metallurgy (PM). Among the advantages with this technique are decreased cost of production for complex-shaped parts, new alloys are made possible, reduced end processing, less material loss, and vibrational damping effects.

  3. 3. Deriving Geothermal Reservoir Properties from Tomographic Models

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Samantha Kim; [2019]
    Keywords : Geothermal reservoir; super-critical fluids; optimization; seismic tomography; effective medium model; Iceland; Geotermisk energi; seismisk; mediummodel; reservoir; spricktäthet; superkritisk vätska optimisering;

    Abstract : The effectiveness of the heat transfer in a geothermal reservoir strongly depends on its temperature, pressure and rock type. A porous and fractured rock is essential to provide a hot fluid circulation to a geothermal power plant. READ MORE

  5. 5. An alarm system for pore pressure measurements in the foundation ofconcrete dams : a case study of Storfinnforsen buttress dam

    University essay from KTH/Jord- och bergmekanik

    Author : Daniel Falcão de Queiroz; [2018]
    Keywords : Buttress dams; dam foundation; pore pressure; alarm system; alarm limits; sliding in the rock mass; uplift pressure; piezometers.; Lamelldammar; dammgrundläggning; portryck; alarm system; alarmgränser; glidning i bergmassan; upptryck; portrycksmätare;

    Abstract : Concrete buttress dams are relatively light structures and less demandingon foundations; because of that, they may have problems with upliftforces and horizontal joints in the area of the dam´s foundation maypresent a failure mode through sliding. The Storfinnforsen dam, thelargest concrete dam in Sweden, had its foundation studied recently andthe discovery of sub-horizontal joints in the bedrock led to the necessityof having the safety of the dam foundation to sliding assessed.
