Measurement of strain induced responses at femoral artery bypass graft junctions

Campbell, Tríona (University of Limerick, 2015)

Femoral artery bypass grafts have a predilection for failure at the distal anastomosis due to restenosis, within a short period of time, the cause of which has been attributed to altered haemodynamics. This study proposes ...
Micromechanical modelling of damage and failure in fibre reinforced composites under loading in the transverse plane

Vaughan, Ted Joseph (University of Limerick, 2011)

Fibre reinforced composites exhibit a gradual damage accumulation to failure, with a multitude of hierarchical dissipative mechanisms responsible for the deterioration of mechanical properties. In order to predict failure ...
Microscale deformation of a tempered martensite ferritic steel:Modelling and experimental study of grain and sub-grain interactions

Golden, Brian J; Li, Dong-Feng; Guo, Yina; Tiernan, Peter; Leen, Sean B; O'Dowd, Noel P. (Elsevier, 2015)

In this paper, a nite-element modelling framework is presented with explicit representation of polycrystalline microstructure for a tempered martensite ferritic steel. A miniature notched specimen was manufactured from ...
Mitigation of biological adhesion to aircraft leading edge surfaces

Kok, Mariana (University of Limerick, 2014)

Contamination caused by insects on aircraft leading edge surfaces can result in premature transition of the boundary layer, leading to an increase in skin friction drag and fuel consumption. Consequently, the use of novel ...
Modelling the relationships between physical risk factors and operator performance in short cycle

Finneran, Aoife (University of Limerick, Department of Manufacturing & Operations Engineering, 2010)

Physical risk factors and their combinations are linked to the causation of Musculo Skeletal Disorders (MSDs) which has implications for on-site operator productivity. Current risk assessment methods have no element to ...
Multiscale characterisation of damage in laminated composite materials under bending loads

Mortell, Daniel J (University of Limerick, 2016)

In-situ micro-mechanical testing of small composite laminates has been carried out under SEM where video recordings allowed examination of the evolution of damage processes at the microscale. Samples are tested under three- ...
New approaches to abdominal aortic aneurysm rupture risk assessment - engineering insights with clinical gain

McGloughlin, Timothy M.; Doyle, Barry J. (Lippincott Williams & Wilkins, 2010)

Abdominal aortic aneurysm (AAA) rupture remains a significant cause of death in the developed world. Current treatment approaches rely heavily on the size of the aneurysm to decide on the most appropriate time for clinical ...
Noninvasive methods of characterising local regional variations in aortic tissue to advance aneurysm rupture risk prediction

Tierney, Áine P. (University of Limerick, 2012)

Abdominal Aortic Aneurysms (AAAs) is a permanent and irreversible dilation of the infrarenal section of the aorta. AAA’s are generally asymptomatic, until rupture of the AAA wall occurs. Rupture can lead to large abdominal ...
A novel operational decision making method for SMES.

Lynch, Andrew (University of Limerick, 2011)

Small to Medium Enterprise (SME) performance is a function of the composite of the decision-making processes within the enterprise. Owner managers are conscious of the gap in their decision-making efficacy and acknowledge ...
Numerical and analytical modelling of strength and toughness of carbon nanotubes and carbon nanotube reinforced nanocomposites

Byrne, Martin Emmett (University of Limerick, 2014)

The exceptional mechanical properties of carbon nanotubes (CNTs) make them highly attractive as potential reinforcing constituents in next generation composites. CNTs can be used as toughening agents in ceramic, metal or ...
A numerical and experimental investigation of the mean and turbulent characteristics of a wing-tip vortex in the near-field

O'Regan, Micheál Seán (University of Limerick, 2014)

Turbulent wing-tip vortices are an extremely important fluid dynamics phenomena for their negative impact in several applications. Despite the many numerical and experimental studies conducted on this particular flow, ...
A numerical investigation of the irradiation of CNT bundles for enhancement of mechanical properties by improved inter-tube coupling

O'Brien, Nathan P. (2014)

The ultra-high stiffness and strength of carbon nanotubes (CNTs), of the order of 1 TPa and 100 GPa respectively, has stimulated intense interest in CNT-based composites, including the development of super strong fibres ...
Numerical modelling of cooling crystallisation: process kinetics to optimisation

Mitchell, Niall A (University of Limerick, 2012)

The research detailed in this dissertation expands the field of knowledge in the area of numerical modelling of cooling crystallisation processes in stirred vessels. The paracetamol and ethanol solution system was chosen ...
Numerical modelling of crystallisation processes: kinetics to optimization

Ó'Ciardha, Clifford Thomás (University of Limerick, 2013)

Crystallisation and precipitation processes are used in the chemical and pharmaceutical industry to produce crystals with desired product properties, such as flow ability, filterability, drying time and bioavailability. ...
Numerical simulation of the L-glutamic acid polymorphic system

Frawley, Patrick J; Scully, James (University of Limerick, Department of Mechanical & Aeronautical Engineering, 2010)

The research detailed in this dissertation expands the field of knowledge in the area of numerical modelling of polymorphic systems and the suspension of polymorphs in stirred tanks. The L-glutamic acid polymorphic system ...
On slip flow and interfacial phenomena within superhydrophobic microchannels

O'Keeffe, Niall (University of Limerick, 2012)

The unique wetting properties of superhydrophobic (SH) surfaces have attracted a considerable interest in recent years. Their ability to repel liquids produces some remarkable characteristics such as spherical droplet ...
On the characterisation of abdominal aortic tissues

O'Leary, Siobhan Ann (University of Limerick, 2014)

Abdominal aortic aneurysm (AAA) is the gradual and irreversible expansion of the distal region of the aorta. It can be defined as a balloon like dilation 1.5 times the diameter of the normal abdominal aorta. The prevalence ...
On the development of assessment techniques for improved prediction of arteriovenous graft performance in facilitating haemodialysis

Broderick, Stephen P (University of Limerick, 2014)

Renal failure is a condition where the kidneys cannot provide sufficient filtration of waste product from the blood. A kidney transplant is the ideal treatment, but donor numbers fall short of demand. The alternative ...
On the effect of digitising flows in networked microfluidic systems for nucleic acid analysis

Taheny, Oliver (University of Limerick, 2010)

The integration of molecular diagnostics and microfluidics has the potential to revolutionise human health care. The continuous discovery of genetic markers that correspond to particular cancer types and subtypes offers ...
On the experimental receptivity in a pre-transitional laminar boundary layer

Brighenti, Flavio (University of Limerick, 2013)

This work is devoted to the study of the influence of the freestream turbulence intensity (FST) on a pre-transitional boundary layer formed on a flat plate. The FST was generated using a passive turbulence-generating ...
