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 on Timber Engineering

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, August). Using the right Modulus of Elasticity to get the best grades out of softwood timber species in Great Britain. Presented at 2016 World Conference on Timber Engineering (WCTE 2016)

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, August). Thinking beyond the usual strength grades – with examples of British spruce and larch. Presented at World Conference on Timber Engineering (WCTE 2016)

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, June). Analysis of acoustical properties of wood and mode identification by sample scanning in the very near field. Presented at 60th Meeting of the Society for Electronics, Telecommunications, Computers, Automatic Control and Nuclear Engineering ETRAN

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...

The timber resource in G. B.-more species for new challenges. (2016)
Presentation / Conference Contribution
Gil-Moreno, D., Ridley-Ellis, D., & McLean, P. (2016, April). The timber resource in G. B.-more species for new challenges. Paper presented at Young Researchers’ Forum III: Innovation in Construction Materials

Timber in Great Britain is mostly produced from Sitka spruce (Picea sitchensis). Biotic threats have led tree growers to consider the planting of a wider range of species to offer a more resilient forest. There is little information on how this will...
