Reinforcement of timber elements in compression perpendicular to the grain using compressed wood dowels
(National University of Ireland Galway, 2020-08-27)
ABSTRACT: In the past decade, there has been an increased focus on the environmental impacts of construction and a movement
towards more sustainable construction products. Timber is one such sustainable product that can ...
Recovered wood as raw material for structural timber products. Characteristics, situation and study cases: Ireland and Spain
(International Society of Wood Science and Technology (SWST), 2020-07-12)
The circular economy is an efficient system to reuse materials reducing the amount of waste generated. In order to implement it in the timber sector, the InFutUReWood (Innovative Design for the Future Use and Reuse of ...
Use of non-destructive test methods on Irish hardwood standing trees and small-diameter round timber for prediction of mechanical properties
(Springer Verlag, 2020-06-17)
Key message Mechanical properties of small-diameter round timber from hardwood thinnings of common alder (Alnus glutinosa (L.) Gaertn.), European ash (Fraxinus excelsior L.), European birch (Betula pendula Roth. & Betula ...
A strain-gradient, crystal plasticity model for microstructure-sensitive fretting crack initiation in ferritic-pearlitic steel for flexible marine risers
(Elsevier, 2018-02-03)
A three-dimensional, strain-gradient, crystal plasticity methodology is presented for prediction of microstructure-sensitive length-scale effects in crack initiation, under fatigue and fretting fatigue conditions, for a ...
The effect of the beta phase on the micromechanical response of dual-phase titanium alloys
(Elsevier, 2017-03-24)
This paper investigates the role of beta phase on the micro-mechanical behaviour of dual-phase titanium alloys, with particular emphasis on the phenomenon of cold dwell fatigue, which occurs in such alloys under room ...
Use of nondestructive techniques for determination of tension parallel-to-grain properties of spruce
(USDA Forest Service Forest Products Laboratory (FPL), 2019-09-25)
The paper presents a study of the tension properties of Irish-grown Sitka spruce. Fifty timber pieces were destructively tested having resonant frequency and knots measured. The aim was to improve knowledge of the performance ...
Relationships between wood properties of small clear specimens and structural-sized boards in three softwood species
(De Gruyter, 2019-06-12)
Research on the mechanical and physical properties of wood is commonly carried out on either small clear specimens or structural-sized boards. The first approach was more frequently utilised in the past, while the latter ...
Numerical study of FRP reinforced timber members subjected to variable climates
(SHATiS International Conference on Structural Health Assessment of Timber Structures, 2019-09-25)
The use of FRP reinforcement, even in small percentages, has been shown to improve the short-term flexural behaviour of timber members. This technology has been successfully used in new construction and in the repair and ...
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 ...
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 ...
