Combined experimental testing and numerical modelling of a novel vertical axis tidal turbine
Mannion, Brian (NUI Galway, 2018-11-30)This research presents a study of a novel vertical axis tidal turbine (VATT) – the GKinetic turbine – using experimental testing of scale devices and numerical modelling. The primary aims of the thesis were: (1) to assess ... -
Damage and permeability in linerless composite cryogenic tanks
Grogan, David M. (2015-09-29)Carbon fibre reinforced polymers (CFRP) are one of the prospective material families being investigated for use in the fuel tanks of future reusable launch vehicles (RLVs). The extreme cryogenic thermo-mechanical loading ... -
Experimental characterisation and computational constitutive modelling of high temperature degradation in 9Cr steels including microstructural effects
Barrett, Richard A. (2016-04-20)The transition from base-load to intermittent power plant operation has led to the requirement for increased knowledge and more accurate prediction of the effects of flexible loading on plant components. This thesis is ... -
Fatigue of Glass Fibre Composites in Marine Renewable Energy
Kennedy, Ciaran R. (2013-10)Glass fibre reinforced polymers (GFRP) are obvious candidate materials for use in the structures of ocean energy devices due to their corrosion resistance, high strength and low cost. The polymers normally used in GFRP can ... -
Fretting wear-fatigue study for tribologically-induced damage in simple and complex geometries
Zhang, Teng (2013-02-22)This thesis presents the development of a computational and experimental methodology for predicting fretting wear-fatigue interaction in simple and complex geometries, specifically targeting the taper-lock assembly in ... -
Micromechanics of fatigue with application to stents
Sweeney, Caoimhe (2014-09-30)This thesis describes the development of a computational framework, based on experimental characterisation and validation, for the microstructure-sensitive modelling of fatigue crack initiation, with a focus placed on its ... -
A Study of Microstructure-Sensitive Crack Nucleation and Wear in Fretting
McCarthy, Oliver J. (2013-07-08)This thesis presents the development of a computational and experimental methodology for predicting crack initiation and wear in fretting of engineering materials. A bridge-type fretting fatigue test rig is designed and ... -
Thermomechanical Analysis of P91 Power Plant Components
Farragher, Tadhg P. (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 ...
