Damage characterisation of cryogenically cycled carbon fibre/PEEK laminates
(Elsevier ScienceDirect, 2014-08-14)A unique insight into damage formation in CF/PEEK laminates before, during and after cryogenic cycling, using optical microscopy and 3D X-ray computed tomography (CT), is presented. Thicker laminates were found to exhibit ... -
Defect evaluation of the honeycomb structures formed during the drilling process
(SAGE Publications, 2019-07-02)In this paper, a comprehensive experimental investigation was carried out to precisely characterize the delamination and uncut fiber in the drilling process. A digital imaging procedure was developed in order to calculate ... -
Deformation mechanisms of selective laser melted 316L austenitic stainless steel in high temperature low cycle fatigue
(Elsevier, 2022-04-22)To investigate the low cycle fatigue (LCF) properties of SLM (Selective laser melting) 316L at 550 °C high temperature, a series of LCF tests at different strain amplitudes is conducted on SLM 316L and traditional 316L. ... -
A design for environment (DFE) product analysis
(2007)Environmental legislation is holding electrical and electronic manufacturers accountable for the disposal of their products at end of life. In order to reduce disposal costs, manufacturers are seeking to optimise product ... -
Design for experience: An analysis of the Irish Creative Industry
(2012)In this paper we report on the results of an exploratory study that investigated the experiences of key informants from SMEs in the Irish creative sector that are involved in design. A purposive sample of 56 small firms ... -
Design of composite tidal turbine blades
(2013-02-24)Tidal turbine blades are subjected to significant thrust and torsional loadings due to the high density ofthe seawater in which they operate. These thrust loadings lead to high bending moments at the bladeroot, which can ... -
A detailed investigation of the impact of an innovative dynamic façade system on indoor environmental quality in offices
(University of Galway, 2023-10-04)In recent years, naturally ventilated glass façades have become a common feature in the design and retrofit of large-scale non-residential buildings, integrating architectural aesthetics and energy efficiency. These ... -
Determinants of Foreign Direct Investment: An analysis of Japanese Investment in Ireland using the Kano model
(IEEE, 2013-06)This paper presents findings from an analysis of the location-specific foreign direct investment (FDI) factors that attract Japanese multinational companies (MNCs) to Ireland. Data was collected from 11 Japanese MNCs and ... -
Developing a scorecard for enterprise knowledge management
(2002-05-19)Enterprise knowledge management is becoming a critical component of competitive success. Managers must ensure that they can successfully generate, leverage and reuse knowledge assets in their organisations. In this view, ... -
Developing a self assessment audit to support product innovation management
(2000)Product innovation is critical to the success of most design and manufacturing enterprises. It is widely recognised that effective co ordination, organisation and management affects product innovation success rates. Self ... -
Development and assessment of a blade element momentum theory model for high solidity vertical axis tidal turbines
(Elsevier, 2020-01-20)Tidal energy is an attractive renewable resource given its predictability. The production of reliable, efficient and cost-effective tidal energy turbines requires the development of computer models for assessment and design ... -
Development of a structured on-the-job training model
(2007)This paper examines the potential of using knowledge management in developing a structured on-the-job training programme. Using a qualitative multiple case study approach, multiple sources of evidence were collected from ... -
The development of a supplier performance evaluation tool
(2005)As product life cycles continue to shrink and global competition increases, manufacturers are outsourcing what they consider to be non-strategic activities in order to focus on their core competencies. Consequently these ... -
Development of life assessment procedures for power plant headers operated under flexible loading scenarios
(Elsevier ScienceDirect, 2013-12-22)A finite element methodology for thermo-mechanical fatigue analysis of a subcritical power plant outlet header under realistic loading conditions is presented. The methodology consists of (i) a transient heat transfer ... -
Development of the meshless finite volume particle method with exact and efficient calculation of interparticle area
(Elsevier, 2014-02-18)The Finite Volume Particle Method (FVPM) is a meshless method based on a definition of interparticle area which is closely analogous to cell face area in the classical finite volume method. In previous work, the interparticle ... -
