An experimental and numerical investigation into the machining of Inconel 718 using coated cemented carbide cutting tools
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2000)The nickel-base superalloy Inconel 718, a tough material capable of maintaining its strength at high temperatures and resisting corrosion in various environments, can be classified as a "difficult to machine" material. Yet ... -
An improved framework for the inverse analysis of skeletal muscle tissue in-vivo
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2012)This thesis focusses on the development of an experimental and computational framework for the non-invasive analysis of the passive mechanical properties of living human skeletal muscle tissue. This is relevant to many ... -
An investigation into the causes of higher rates of restenosis in peripheral arteries compared with coronary arteries following stenting
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2010)The use of stenting in peripheral arteries has been limited by rates of in-stent restenosis and stent fracture considerably higher than seen in coronary arteries. Traditional balloon expandable stainless steel stents were ... -
An investigation into the influence of cardiovascular stent design on the development of restenosis using the finite element method
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2004)Finite element models, which can determine the degree of vascular injury caused to a vessel by a stent and hence ascertain the propensity of that stent design to cause in¬stent restenosis, would be a valuable tool for both ... -
An investigation into the role of substrate stiffness and oxygen availability in the regulation of stem cell differentiation during tissue regeneration
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2013)Mesenchymal stem cells (MSCs) are multipotent cells which can differentiate down multiple lineages and potentially generate tissues such as cartilage, bone or adipose tissue. It is becoming increasingly clear that mechanical ... -
An investigation of joint tissue derived stem cells for articular cartilage tissue engineering
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)Tissue engineering has emerged as a promising approach to repair damaged articular cartilage. The associated drawbacks with the isolation and expansion of chondrocytes from autologous tissue have prompted significant ... -
An investigation of structure-function relations in articular cartilage during skeletal maturation
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2013)The over-riding objective of this thesis was to build upon our current understanding of the evolving nature of articular cartilage mechanics by elucidating how changes to structure and composition of the tissue during ... -
An optimized surface topography for calcium phosphate bone tissue engineering scaffolds
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2016)Improved scaffold/host integration and avoiding core necrosis are important and active goals in tissue engineering. Alternatives to bone tissue grafting that are highly bioactive and inexpensive to manufacture are clinical ... -
Analysis of a Wide Range of Commercial Exterior Wood Coatings
(MDPI AG, 2020)This study was focused on measuring the properties of twenty-three commercially available coatings formulated for exterior wood applications. The coatings were characterized by measuring their surface tension, solid content, ... -
Analysis of noise source mechanisms for a subsonic jet
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2006)Despite advances in engine design, from high bypass to co-axial or lobe shaped nozzles, the problem of jet noise reduction continues to require ongoing research in order to comply with the criteria inherent in environmental ... -
Analysis of the elastic and inelastic behaviour of healthy and diseased arterial tissue
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2012)Mechanical factors play a key role in determining the success of clinical procedures such as balloon angioplasty and stenting that aim to increase lumen size in atherosclerotic lesions. Finite element modelling is commonly ... -
Analysis of the Potential of DynaFlexPro as a Modeling Software by its Application in the Roll Stability of Heavy-Duty Elliptical Tankers using Trammel Pendulum to Simulate Fluid Sloshing
(Trinity College Dublin. School of Engineering. Mechanical & Manufacturing Engineering, INSA Lyon, 2007)One of the most common ways for commercial vehicles to loose their stability is by rollover. Partially filled heavy-duty tankers manoeuvring constant radius turns or lane change maneuvers have lower rollover threshold than ... -
Analysis of the rough contact in axisymmetric upsetting
(Trinity College Dublin. School of Engineering. Mechanical & Manufacturing Engineering, 2007)Characterization of surface roughness is important in the frictional behavior of two contact surfaces. In general, it has been found that friction increases with average roughness. The prediction of friction and stress/ ... -
Analysis of tool cavity stresses in channel angular extrusion
(2006)The Channel Angular Extrusion (CAE) technique is a process, in which a deformable solid material is led to yielding through the intersection of inclined c hannels. Compared to classic plastic deformation, ... -
Analytical heat conduction model of annular composite fins
(2018)A two-dimensional analytical heat conduction model of an annular composite fin has been carried out.The composite fins composed of a porous polyethylene core, a square aluminum insert,and metallic zinc coating layers, ... -
An anisotropic inelastic constitutive model to describe stress softening and permanent deformation in arterial tissue
(2012)Inelastic phenomena such as softening and unrecoverable inelastic strains induced by loading have been observed experimentally in soft tissues such as arteries. These phenomena need to be accounted for in constitutive ... -
The anisotropic mechanical behaviour of passive skeletal muscle tissue subjected to large tensile strain
(2013)The passive mechanical properties of muscle tissue are important for many biomechanics applications. However, significant gaps remain in our understanding of the three-dimensional tensile response of passive skeletal ...
