Void distributions and permeability prediction for rotationally moulded polymers
(SAGE, 2014-01-22)
An experimental study of void distributions for rotationally moulded polyethylene is presented. The effects of key variables such as maximum process temperature and nominal wall thickness (via powder mass) are studied. ...
A preliminary design methodology for fatigue life prediction of polymer composites for tidal turbine blades
(SAGE, 2012-06-06)
Tidal turbine blades experience significant fatigue cycles during operation and it is expected that fatigue strength will be a major consideration in their design. Glass fibre reinforced polymers are a candidate low-cost ...
An experimental study on the key fretting variables for flexible marine risers
(Elsevier, 2017-07-02)
This paper presents an experimental investigation into the effects of contact
conformity, contact pressure and displacement amplitude on the gross-slip fretting behaviour grease-lubricated cylinder-on-flat contacts in the ...
Microstructure modeling of high-temperature microcrack initiation and evolution in a welded 9Cr martensitic steel
(SAGE Publications, 2019-02-28)
Welded joints in tempered 9Cr-1Mo operating at elevated temperatures are well known to be prone to premature failure due to cracking in the heat-affected zone. This paper describes a crystal plasticity model to predict the ...
A comparison of two quasi-static computational models for assessment of intra-myocardial injection as a therapeutic strategy for heart failure
(Wiley, 2019-05-06)
Myocardial infarction, or heart attack, is the leading cause of mortality globally. Although the treatment of myocardial infarct has improved significantly, scar tissue that persists can often lead to increased stress and ...
Physical experimental static testing and structural design optimisation for a composite wind turbine blade
(Elsevier, 2016-12-10)
This study presents experimental testing on a 13 m long glass-fibre epoxy composite wind turbine blade. The results of the test were used to calibrate finite element models. A design optimisation study was then performed ...
Validation of the multi-objective structural optimisation of a composite wind turbine blade
(Elsevier, 2018-08-01)
Structural optimisation of a wind turbine blade is presented in this work. The optimisation was performed using a multi-objective genetic algorithm and finite element modelling to determine the optimal structural design ...
Experimental and computational characterization of the effect of manufacturing-induced defects on high temperature, low-cycle fatigue for MarBN
(Elsevier, 2020-05-22)
Manufacturing-induced defects are a key source of crack initiation and component failure under high temperature cyclic loading. In this work, 3D X-ray micro-computed tomography and microstructural analysis of manufacturing-induced ...
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 ...
Effect of high-temperature corrosion on the service life of P91 piping in biomass co-firing
(American Society of Mechanical Engineers (ASME), 2016-02-24)
Co-firing biomass with traditional fuels is becoming increasingly relevant to thermal power plant operators due to increasingly stringent regulations on greenhouse gas emissions. It has been found that when biomass is ...
