Finite element modelling of the thermo-mechanical behaviour of a 9Cr martensitic steel
(Springer, Berlin, Heidelberg, 2013-01-01)A multi-axial, unified sinh viscoplastic material model has been developed to model the behaviour of advanced materials subjected to high temperature cyclic loading. The material model accounts for rate-dependent effects ... -
Finite element prediction of creep-plastic ratchetting and low cycle creep-fatigue for a large SPF tool
(Springer Verlag, 2010-03-03)Industrial experience shows that large superplastic forming (SPF) tools suffer from distortion due to thermal cycling, which apparently causes high temperature creep and plasticity. In addition to distortion, thermomechanical ... -
Finite element simulation and experimental validation of fretting wear
(Elsevier, 2003-10-30)A finite element-based method is presented for simulating both the fretting wear and the evolution of fretting variables with number of wear cycles in a cylinder-on-flat fretting configuration for application to aeroengine ... -
Finite element simulation of fretting wear and fatigue in thin steel wires
(Elsevier ScienceDirect, 2013-05-09)This paper studies the effect of fretting on fatigue life reduction of thin steel wires, using the frictionally-induced multiaxial contact stresses obtained from a finite element wear model, validated in previous work. The ... -
A finite element study of microstructure-sensitive plasticity and crack nucleation in fretting
(Elsevier ScienceDirect, 2011)This paper is concerned with finite element modelling of microstructure-sensitive plasticity and crack initiation in fretting. The approach adopted is based on an existing method for microstructure-sensitive (uniaxial) ... -
A finite element-based approach for predictions of rigid pile group stiffness efficiency in clays
(Springer Verlag, 2013-08-17)This paper presents a finite element parametric study of several variables that affect the stiffness efficiency of rigidly capped pile groups with a view to developing a solution for preliminary design purposes. Previous ... -
Flexural reinforcement of glue-laminated timber beams using prestressed FRP plates.
(NetComposites Limited, 2009-09-01)Fibre-reinforced polymer (FRP) plates have been used successfully to enhance the structural performance of glue-laminated (glulam) timber beams. Unreinforced glulams usually fail in tension in a brittle fashion. The addition ... -
Flipped learning in a civil engineering module: student and instructor experiences
(Irish Learning Technology Association, 2018-08-24)Flipped learning is a form of active learning in which the basic content is assimilated before scheduled classroom sessions, enabling more productive use of classroom time to cultivate problem-solving ability, a key ... -
Fluid dynamics of gas exchange in high-frequency oscillatory ventilation: In vitro investigations in idealized and anatomically realistic airway bifurcation models
(Springer, 2008-11)The objective of this work is to develop understanding of the local fluid dynamic mechanisms that underpin gas exchange in high-frequency oscillatory ventilation (HFOV). The flow field during HFOV was investigated ... -
Fluid flow in the osteocyte mechanical environment: a fluid-structure interaction approach
(Springer Verlag, 2013-04-09)Osteocytes are believed to be the primary sensor of mechanical stimuli in bone, which orchestrate osteoblasts and osteoclasts to adapt bone structure and composition to meet physiological loading demands. Experimental ... -
A Fluorescently Labeled, Hyperbranched Polymer Synthesized from DE-ATRP for the Detection of DNA Hybridization
(Royal Society of Chemistry, 2012-01)The early detection of oligonucleotide biomarkers of disease, such as microRNAs, has been established as a fundamental factor in cancer diagnosis. As the levels of these small molecules (microRNAs) in blood have recently ... -
Follow flee: A contingent mobility strategy for the spatial prisoner's dilemma
(Springer Verlag, 2016-08-10)This paper presents results from a series of experimental simulations comparing the performances of mobile strategies of agents participating in the Spatial Prisoner's Dilemma game. The contingent movement strategies Walk ... -
Formal Calibration methodology for a CFD model of a naturally ventilated room
(2011)This paper describes a systematic methodology for the development of calibrated thermodynamic Computational Fluid Dynamics (CFD) models for controlled environments in buildings utilising wireless sensor networks. ... -
Formal calibration methodology for CFD model development to support the operation of energy efficient buildings
(Texas A&M University, 2010)Computational Fluid Dynamics (CFD) is a robust tool for modelling interactions within and between fluids and solids. CFD can help understand and predict phenomena that are difficult to test experimentally leading ... -
Formal calibration methodology for CFD models of naturally ventilated indoor environments
(Elsevier, 2012-08-31)Well planned natural ventilation strategies and systems in the built environments may provide healthy and comfortable indoor conditions, while contributing to a significant reduction in the energy consumed by buildings. ... -

A framework for determining unsaturated zone time lags at catchment scale
(Elsevier Masson, 2016-12-10)The responses of waterbodies to agricultural programmes of measures are frequently delayed by hydrological time lags through the unsaturated zone and groundwater. Time lag may therefore, impede the achievement of remediation ... -
A Framework for Digital Wide-Area Survey from Aerial Photographs
