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 ... -
A preliminary design methodology for fatigue life prediction of polymer composites for tidal turbine blades
(SAGE, 2012-07)Tidal turbine blades experience significant fatigue cycles during operation and it is expected that fatigue strength will be a major consideration in their design. Glass fibre reinforced polymers are a candidate low-cost ... -
A preliminary design methodology for fatigue life prediction of polymer composites for tidal turbine blades
(SAGE, 2012-06-06)Tidal turbine blades experience significant fatigue cycles during operation and it is expected that fatigue strength will be a major consideration in their design. Glass fibre reinforced polymers are a candidate low-cost ... -
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 ... -
Strain-gradient modelling of grain size effects on fatigue of CoCr alloy
(Elsevier, 2014-07-30)A strain-gradient crystal plasticity framework based on physical dislocation mechanisms is developed for simulation of the experimentally observed grain size effect on the low cycle fatigue of a CoCr alloy. Finite-element ... -
The tensile ductility of cellular solids: the role of imperfections
(Elsevier, 2016-10-11)Metallic and polymeric foams typically possess a low tensile failure strain of a few percent despite the fact that the parent solid can have high ductility (10% or more). This is remarkable as foams are bending-dominated ... -
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 ... -
Web geometry optimisation of novel latticed LVL-webbed timber I-joists
(Elsevier, 2022-12-02)This paper presents the finite element analysis of novel composite timber I-joists with curved latticed webs. The flanges of the joists were made from Norway Spruce whilst the curved latticed webs were made from laminated ...
