  1. 1. The Effect of Chloride-Induced Corrosion Patterns on the Crack Width of Reinforced Concrete

    Master-uppsats, KTH/Betongbyggnad

    Författare :Dilara Uludag; [2023]
    Nyckelord :;

    Sammanfattning : This master's thesis investigates cracking in a parking garage, with a particular focus on the influence of corrosion. Concrete structures commonly experience cracking, and corrosion has emerged as one of the primary contributing factors. These cracks, varying in size and shape, can be considered structural discontinuities. LÄS MER

  3. 2. Permanent Fire Load of the Building Envelope

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Gizelle Danine Pondevida Jamero; [2023]
    Nyckelord :Permanent fire load; temporary fire load; fire load; building envelope; insulation; building content; upholstered furniture; heat of combustion; MCC; bomb calorimeter; cone calorimeter; room corner test.; Technology and Engineering;

    Sammanfattning : Fire load, the total thermal energy released by the combustion of a material, is an essential part of determining a building’s fire performance and the associated fire protection strategies. Elements in a structure are typically categorized into two types of fire loads: permanent and temporary. LÄS MER

  4. 3. Numerical analysis of a bearing strength in delaminated composite joint

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Olavi Kukkonen; [2023]
    Nyckelord :Bearing strength; Single-lap shear; Delamination; Countersinking; Hole size;

    Sammanfattning : Composite structures are commonly joined using adhesive or mechanical joints, withmechanical joints being preferred when components need to be removable for maintenancepurposes. However, the presence of mechanical joints introduces a discontinuity in theload path, which can serve as an initiation point for failure and needs to be taken intoaccount in the design of the joint.

  5. 4. Use of Pulse Thermography for Characterization of Defects in Polymer Composites

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Kim Klöckner; [2023]
    Nyckelord :NDT; Pulse Thermography; polymer composites; boats manufacturing; end-of-life structures; defect characterization;

    Sammanfattning : In this project, the possibility of using thermography as a non-destructive testing tool in the manufacturing process of boats and to assess the quality of end-of-life composite structures has been explored. To do so, a literature surview regarding the current applications of thermography and the techniques currently used for quality control in the boats industry has been conducted. LÄS MER

  7. 5. Influence of Surface Carbon Content on the Wear of Threaded Connections in Rock Drilling Steels

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Andreas Hälsing; [2023]
    Nyckelord :carbon content; wear performance; carburized steel; dry contact interface; threaded connections; drill rods; samples; shot peening; production process; twin-disc wear tester; RPM; operating conditions; wear rate; surface topography; hardness; optical analysis; light optical microscopy; scanning electron microscopy; surface carbon content; microstructural changes; frictional heat; contact pressure; wear mechanisms; plastic deformation; adhesive scratching; material removal; delamination;

    Sammanfattning : This thesis work was conducted at Luleå University of Technology in collaboration with Sandvik Rock Tools. The aim of the work was to determine the influence of carbon content on the wear performance in carburized steel in the dry contact interface of threaded connections between drill rods. LÄS MER
