Using the right Modulus of Elasticity to get the best grades out of softwood timber species in Great Britain
Conference Proceeding

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. Th...

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, Vienna, Austria
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 re...

The timber resource in G. B.-more species for new challenges. Paper presented at Young Researchers’ Forum III: Innovation in Construction Materials, London, UK
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 o...
Comparing usefulness of acoustic measurements on standing trees for segregation by timber stiffness.
Conference Proceeding

Comparing usefulness of acoustic measurements on standing trees for segregation by timber stiffness. In R. J. Ross, R. Gonçalves, & X. Wang (Eds.), Proceedings: 19th International Nondestructive Testing and Evaluation of Wood Symposium (378-385
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 prope...
