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...

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...

Comparing usefulness of acoustic measurements on standing trees for segregation by timber stiffness. (2015)
Presentation / Conference Contribution
Gil-Moreno, D., & Ridley-Ellis, D. (2015, September). Comparing usefulness of acoustic measurements on standing trees for segregation by timber stiffness. Presented at 19th International Nondestructive Testing and Evaluation of Wood Symposium, Rio de Janeiro, RJ, Brazil

The paper presents a comparison of standard procedures to measure acoustic stiffness of standing trees and logs. The aim is to see how useful they are for predicting the properties of dry, sawn, timber for the purposes of resource segregation in indu...
