Modelling of fretting in the pressure armour layer of flexible marine risers
(Elsevier, 2016-03-04)
This paper presents a computational methodology for frictional contact mechanics of the pressure armour layer in flexible risers. This will allow, for the first time, quantification of key fretting variables, such as contact ...
Statistical grain size effects in fretting crack initiation
(Elsevier, 2016-09-20)
A crystal plasticity computational framework is developed and validated to investigate the microstructure sensitivity of crack initiation in fretting. Randomly distributed microstructure geometries are incorporated into a ...
A combined wear-fatigue design methodology for fretting in the pressure armour layer of flexible marine risers
(Elsevier, 2016-10-20)
This paper presents a combined experimental and computational methodology for fretting wear-fatigue prediction of pressure armour wire in flexible marine risers. Fretting wear, friction and fatigue parameters of pressure ...
The effects of planting density on the structural timber properties of 23-year-old Irish-grown Sitka spruce
(NUI Galway, 2016-08-29)
In Europe, with the move towards more sustainable construction, there is an increasing demand for structural timber. The
purpose of this research is to explore new forestry management strategies, which will produce an ...
Viscoelastic creep of FRP reinforced glulam
(NUI Galway, 2016-08-29)
The reinforcement of timber using fibre reinforced polymer (FRP) rods or plates is widely accepted as an effective
method of increasing the strength and stiffness of members, while at the same time reducing the variability ...
Evaluation of the structural behaviour of beam-beam connection systems using compressed wood dowels and plates
(NUI Galway, 2018-08-20)
To support the transition to a bio-based society, it is preferable to substitute metallic fasteners and adhesives in timber construction with an eco-friendly alternative. Recent studies have identified compressed wood ...
The effect of thinning on mechanical properties of Douglas fir, Norway spruce, and Sitka spruce
(Springer Verlag, 2019-01-07)
Context: The relationship between silvicultural management and the quality of timber produced is not entirely elucidated.
Aims: The effects of thinning on structural grade-determining properties of wood (elastic modulus, ...
The influence of crown and stem characteristics on timber quality in softwoods
(Elsevier, 2018-12-28)
The relationships between several crown and tree properties and timber quality were examined on three softwood species: Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), Norway spruce (Picea abies (L.) H. Karst) and Sitka ...
An investigation of the viscoelastic creep behaviour of basalt fibre reinforced timber elements
(Elsevier, 2018-08-01)
An investigation was carried out to examine the effect of flexural reinforcement on the long-term behaviour of timber beams. Creep tests, utilising statistically matched groups, were performed under Service Class 1 conditions ...
Quantification of heat losses through building envelope thermal bridges influenced by wind velocity using the outdoor infrared thermography technique
(Elsevier, 2017-09-18)
Improving the thermal performance of the existing building stock is essential to significantly reduce the overall energy consumption in the building sector. A key objective is the retrofitting of the existing building ...
