Computational modelling of dynamic recrystallisation of Ni-based superalloy during linear friction welding
(Springer, 2022-01-12)Linear friction welding (LFW) is an advanced joining technology used for manufacturing and repairing complex assemblies like blade integrated disks (blisks) of aeroengines. This paper presents an integrated multiphysics ... -
Computational simulation of the relaxation of local stresses due to foreign object damage under cyclic loading
(2010)In this study, the phenomenon of residual stress relaxation from foreign object damage (FOD) is numerically simulated using a hybrid explicit¿implicit finite-element method. The effects of cycle fatigue loadings on stress ... -
Computational study on the effect of contact geometry on fretting behaviour
(Elsevier ScienceDirect, 2011-07-23)A key challenge in the design of engineering couplings and contacting components relates to the development of an understanding of the comparative performance of contrasting contact geometries for a given application, ... -
Cosmic sounds: A game to support phonological awareness skills for children with dyslexia
(2022)Studies show that reduced literacy skills can negatively influence a child¿s self-esteem and future career opportunities. Literacy is significantly affected when problems exist understanding the phonological component or ... -
Creativity toolkit for R&D managers
(2004)In this, the twenty first century, innovation has become one of the most important and effective ways of obtaining and sustaining competitive dominance in the market place over the past number of years. Many firms are ... -
A critical analysis of plastic flow behaviour in axisymmetric isothermal and Gleeble compression testing
(Elsevier ScienceDirect, 2010-08-16)Coupled thermo-mechanical finite element modelling of both isothermal axisymmetric compression and compression testing using the Gleeble thermo-mechanical simulator has been carried out in order to compare the levels of ... -
A customer centric process innovation toolkit for SMEs
(2006)The business environment is changing at an accelerated pace. Consequently, continuous systemic changes within companies are imperative. In light of this, we are witnessing a shift in the way organizations are designed, ... -
Cyclic plasticity of welded P91 material for simple and complex power plant connections
(Elsevier, 2016-02-10)This paper focuses on with the cyclic plasticity modelling of welded, ex-service P91 material. A multi material model is developed for high temperature cyclic plasticity, including the effects of the three different material ... -
Cyclic thermo-mechanical material modelling and testing of 316 stainless steel
(Elsevier ScienceDirect, 2010-04-20)A programme of cyclic mechanical testing of a 316 stainless steel, at temperatures of up to 600 C under isothermal conditions, for the identification of material constitutive constants, has been carried out using a ... -
Cyclic viscoplasticity testing and modelling of a service-aged P91 steel
(American Society of Mechanical Engineers, 2014-04-16)A service-aged P91 steel was used to perform an experimental program of cyclic mechanical testing in the temperature range of 400 °C–600 °C, under isothermal conditions, using both saw-tooth and dwell (inclusion of a ... -
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 ... -
