  • On the use of indentation technique to assess fracture properties of ceramics at the microscale 

    Payraudeau, Nathalie (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)
    Classic methods to determine fracture properties of ceramics (like Single-Edge Notched Beam or Compact Tension) are accurate at the macroscale but inappropriate to estimate local fracture properties which are decisive at ...
  • Optimisation of process parameters and tooling during friction stir welding of AA2024-T3 

    Trimble, Daniel (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)
    Friction stir welding (FSW) was invented and experimentally proven at The Welding Institute (TWI) in 1991. The process involves the joining of two metal pieces without melting by joining their molecules together. The tool ...
  • Passive mechanical properties of skeletal muscle in compression 

    Van Loocke, Mélanie (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2007)
    The compressive properties of skeletal muscle are of prime interest in applications where muscle tissue is submitted to compressive loads; e.g., to improve the design of protective equipment for vehicular occupants, to ...
  • Polymer / clay nanocomposites 

    Istrate, Oana-Mihaela (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2012)
    Polymer/clay nanocomposites are a new class of materials with unique properties that are not shared by the pristine polymers or the conventional composites. These materials may present enhanced mechanical, themial, barrier ...
  • Power and position-oriented process monitoring of freeform abrasive machining 

    Brazel, Emma (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2013)
    Abrasive machining is used for the generation of freeform femoral implant surfaces in the biomedical industry. The abrasive machining operation is typified by high speed material removal in multiple axes, difficult-to-machine ...
  • Prediciton of fatigue failure in engineering components using the finite element method 

    Wang, Ge (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2000)
    Prediction of fatigue failure in engineering artefects is becoming increasingly important as we enter the third millennium; more catastrophic fatigue failures will occur as engineers push the limits of design even further ...
  • Predictions of Rotor Broadband Noise 

    Botha, Jason (Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2018)
    This thesis presents an enhanced method for predicting aerodynamically generated broadband noise, produced by rotating machinery. The method improves on existing work for Vertical Axis Wind Turbine (VAWT) noise prediction, ...
  • Process, precedent, and community : new learning environments for engineering design 

    Holland, Dónal (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2014)
    Project-based design courses are an increasingly conunon component of engineering education. Most engineering schools have traditionally emphasized the analytical and scientific aspects of the discipline, and an increase ...
  • Quantitative accoustic analysis of inhaler sounds for the objective assessment of inhaler adherence in patients with chronic respiratory diseases 

    Holmes, Martin S. (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2016)
    Asthma and chronic obstructive pulmonary disease (COPD) are two of the most prevalent chronic respiratory disorders. Over 800 million people suffer from these diseases and over four million people die annually. Although ...
  • Reconfigurable manufacturing process monitoring systems 

    Morgan, Jeff (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2016)
    Performance measurement is indispensable to manufacturing, due to the fact that if the efficiency of an activity cannot be measured it could not be effectively controlled. Recent trends in process monitoring systems point ...
