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 ...
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 ...
Evaluating long-term performance of low-cost adsorbents using small-scale adsorption column experiments
(Elsevier, 2016-05-31)
This study investigated a novel method of predicting the long-term phosphorus removal performance of large-scale adsorption filters, using data derived from short-term, small-scale column experiments. The filter media ...
The short-term effects of management changes on watertable position and nutrients in shallow groundwater in a harvested peatland forest
(Elsevier, 2014-09-01)
Management changes such as drainage, fertilisation, afforestation and harvesting (clearfelling) of forested peatlands influence watertable (WT) position and groundwater concentrations of nutrients. This study investigated ...
Improving the finite element model accuracy of tissue engineered scaffolds produced by selective laser sintering
(Springer Verlag, 2015-01-13)
In bone tissue engineering, both geometrical and mechanical properties of a scaffold play a major part in the success of the treatment. The mechanical stresses and strains that act on cells on a scaffold in a physiological ...
Comparing coronary stent material performance on a common geometric platform through simulated bench testing
(Elsevier ScienceDirect, 2012-03-02)
Absorbable metallic stents (AMSs) are a newly emerging cardiovascular technology which has the potential to eliminate long-term patient health risks associated with conventional permanent stents. AMSs developed to date ...
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 ...
Investigation of histology radius for dielectric characterisation of heterogeneous materials
(Institute of Electrical and Electronics Engineers, 2018-07-13)
Knowledge of the dielectric properties of biological tissues is fundamental in the design of novel electromagnetic-based medical devices. Tissue dielectric properties are typically measured using the open-ended coaxial ...
Micro-scale testing and micromechanical modelling for high cycle fatigue for CoCr stent material
(Elsevier ScienceDirect, 2015-02-20)
This paper presents a framework of experimental testing and crystal plasticity micromechanics for high cycle fatigue (HCF) of micro-scale L605 CoCr stent material. Micro-scale specimens, representative of stent struts, are ...
A physical corrosion model for bioabsorbable metal stents
(2014)
Absorbable metal stents (AMSs) are an emerging technology in the treatment of heart disease. Computational modelling of AMS performance will facilitate the development of this technology. In this study a physical corrosion ...
