An update on grading timber for structural use (2017)
Book Chapter
Mansfield-Williams, H., & Ridley-Ellis, D. (2017). An update on grading timber for structural use. In TRADA Timber Industry Yearbook 2017 (148-155)

The quality of timber varies and, while we have little control over tree growth compared to industrial manufacturing processes, we do know many of the factors that influence wood properties. Both the species and the growth region are important since... Read More about An update on grading timber for structural use.

Timber properties of noble fir, Norway spruce, western red cedar and western hemlock grown in Great Britain (2016)
Report
Gil-Moreno, D., Ridley-Ellis, D., & McLean, P. (2016). Timber properties of noble fir, Norway spruce, western red cedar and western hemlock grown in Great Britain. Great Britain: Forest Research

The softwood processing sector in Great Britain has been built around the use of a very small number of timber producing species – predominantly Sitka spruce. The recent increase in outbreaks of host-specific tree pests and diseases has led to an int...

Combining of results from visual inspection, non-destructive testing and semi-destructive testing to predict the mechanical properties of Western Hemlock (2016)
Presentation / Conference Contribution
Bather, M., Ridley-Ellis, D., & Gil-Moreno, D. (2016, August). Combining of results from visual inspection, non-destructive testing and semi-destructive testing to predict the mechanical properties of Western Hemlock. Paper presented at World Conference o

Current methods of assessing the mechanical properties of in-situ timber are limited, particularly with regard to estimating bending strength and stiffness. The aim of this research is to combine non-destructive testing (NDT), visual inspection and t...

Using the right Modulus of Elasticity to get the best grades out of softwood timber species in Great Britain (2016)
Presentation / Conference Contribution
Gil-Moreno, D., Ridley-Ellis, D., & McLean, P. (2016). Using the right Modulus of Elasticity to get the best grades out of softwood timber species in Great Britain. In WCTE 2016 World Conference on Timber Engineering e-book Full Papers

The correct characterisation of modulus of elasticity in bending is fundamental for timber grading, especially when that property limits the allocation to a strength class. The aim of this paper is to empirically determine the relationship between EN...

Thinking beyond the usual strength grades – with examples of British spruce and larch (2016)
Presentation / Conference Contribution
Ridley-Ellis, D., Adams, S., & Lehneke, S. (2016). Thinking beyond the usual strength grades – with examples of British spruce and larch. In Proceedings of the World Conference on Timber Engineering (WCTE 2016), August 22-25, 2016, Vienna, Austria, Eds

This paper summarises the processes and normative requirements involved in grading of structural timber, and outlines a number of areas in which matters may be improved, so as to make better use of the true properties of the timber resource used. The... Read More about Thinking beyond the usual strength grades – with examples of British spruce and larch.

Analysis of acoustical properties of wood and mode identification by sample scanning in the very near field (2016)
Presentation / Conference Contribution
Pantelić, F., Šumarac Pavlović, D., Mijić, M., & Ridley-Ellis, D. (2016). Analysis of acoustical properties of wood and mode identification by sample scanning in the very near field. In Zbornik apstrakata i program 60.konferencije ETRAN, Zlatibor

It is possible to achieve a good visualization of vibration modes by microphone scanning of a vibration excited sample of wood in very near field. The experimental settings, shown in this paper, were used for wood properties characterization and obse...
