Computational and experimental analysis of the mechanical performance of SLS generated polymer-ceramic bone scaffold materials
(2014-09-30)The load-bearing ability of orthopaedic scaffolds in critical-sized defects is of critical importance. 3D printing methods such as selective laser sintering (SLS) have great potential for the fabrication of patient-specific ... -
A computational and experimental investigation of tracheobronchial stent performance
(2017-05-25)Tracheobronchial stents are used to relieve blockages in the respiratory tree, typically caused by lung cancer. However, multiple complications can be associated with stents for this indication. In order to be able to ... -
Cortical Bone Fracture and Orthopaedic Fixation Devices: An Experimental and Computational Investigation
(2012-09-28)An experimental and computational investigation of cortical bone failure mechanisms has been conducted in this thesis. Firstly, a computational comparison of four methods of proximal humeral fracture fixation was conducted. ... -
Experimental and computational investigation into mechanobiology of osteocytes
(2014-10-31)Osteocytes are terminally differentiated bone cells, derived from osteoblasts, which comprise over 90% of the cells in mature bone tissue and are known to be highly sensitive to extracellular mechanical cues. The effect ... -
Experimental and computational investigation of the impact of distorted stent expansion on the performance of transcatheter aortic valve replacements
(2014-12-22)Patients with calcific aortic valve stenosis present with calcium deposits on the aortic valve, which can result in non-circular and distorted expansion of self-expanding Transcatheter Aortic Valve Replacements. The effect ... -
Microstructural functionally graded Ti-6Al-4V via advanced laser-based technologies
(NUI Galway, 2021-11-10)Functionally graded material (FGM) is characterised by an intended spatial variation in material attributes within a single part. This thesis is focused on advanced laser-based manufacturing technologies of microstructural ... -
Non-linear anisotropic mechanical behaviour of hard and soft tissues
(2015-09-30)The overall objective of this thesis is to develop accurate and rigorous constitutive formulations for the non-linear anisotropic behaviour of soft tissue (arterial) and hard tissues (trabecular bone) at large strains. The ... -
The Role of the Actin Cytoskeleton in the Response of Chondrocytes to Mechanical Loading: A Computational and Experimental Investigation
(2012-09-28)The biomechanisms which govern the response of chondrocytes to mechanical stimuli are poorly understood. This thesis aims to provide a more in depth understanding of chondrocyte biomechanics by focusing on the role of actin ... -
Thermomechanical Analysis of P91 Power Plant Components
(2014-01-17)This thesis presents a combined experimental and computational study on the thermo-mechanical fatigue performance of welded P91 material to (i) characterise the thermomechanical behaviour, and (ii) predict the number of ... -
Through-process characterisation for welding, microstructure evolution and constitutive response of 9Cr steel material for flexible power plant operation
(NUI Galway, 2020-05-06)This thesis presents a combined experimental and computational characterisation programme of work for development of a through-process modelling methodology for the welding, post-weld heat treatment and in-service performance ...
