Journal Article
Moore, J. R., Mochan, S. J., Brüchert, F., Hapca, A. I., Ridley-Ellis, D., Gardiner, B. A., & Lee, S. . J. (2009). Effects of genetics on the wood properties of Sitka spruce growing in the UK: bending strength and stiffness of structural timber. Forestry, 82, 491-501. https://doi.org/10.1093/forestry/cpp018

Mechanical tests were conducted on structural timber from a 37-year-old Sitka spruce (Picea sitchensis (Bong.) Carr), progeny trial located in Kershope Forest, Cumbria, UK. Values of modulus of rupture (MOR) and global modulus of elasticity (MOEG) in...

Determination of shear strength of timber joists by torsion testing. (2009)
Presentation / Conference Contribution
Khokhar, A. M., Zhang, H., & Ridley-Ellis, D. (2009, October). Determination of shear strength of timber joists by torsion testing

This paper presents an experimental investigation in which the torsion testing approach was employed to evaluate the shear strength of Sitka spruce and Norway spruce joists. Rectangular
structural size specimens of lengths ranging from 1.0 m to 3.6... Read More about Determination of shear strength of timber joists by torsion testing..

The use of acoustic-based NDT to predict the wood properties of UK-grown Sitka spruce at different stages in the wood supply chain. (2009)
Presentation / Conference Contribution
Moore, J., Lyon, A. J., Searles, G. J., & Ridley-Ellis, D. (2009, May). The use of acoustic-based NDT to predict the wood properties of UK-grown Sitka spruce at different stages in the wood supply chain. Presented at 16th International Nondestructive Testing and Evaluation of Wood Symposium, Beijing, China

This paper is concerned with the extent to which portable stress-wave-based instruments can be used to segregate Sitka spruce trees and logs; in particular the relationship between acoustic velocity and the properties of sawn timber. Measurements wer... Read More about The use of acoustic-based NDT to predict the wood properties of UK-grown Sitka spruce at different stages in the wood supply chain..

Strategic Integrated Research in Timber: Getting the most out of the UK's timber resource. (2009)
Journal Article
Ridley-Ellis, D., Moore, J., Lyon, A. J., Searles, G. J., & Gardiner, B. A. (2009). Strategic Integrated Research in Timber: Getting the most out of the UK's timber resource. Non-conventional Materials and Technologies,

Sitka spruce (Picea sitchensis) is the United Kingdom’s main commercial tree species accounting for nearly one-third of the UK's total woodland area and half of its conifer estate. Sawn timber from this species readily grades to the C16 strength clas... Read More about Strategic Integrated Research in Timber: Getting the most out of the UK's timber resource..

Random acts of elasticity: MoE, G and EN408. (2009)
Presentation / Conference Contribution
Ridley-Ellis, D., Moore, J., & Khokhar, A. M. (2009, April). Random acts of elasticity: MoE, G and EN408

The paper examines the variation in modulus of elasticity (MoE) and shear modulus (G) within sawn timber and the implications for testing timber in accordance with EN408:2003. A combination of mechanical testing and simple analytical modelling is us... Read More about Random acts of elasticity: MoE, G and EN408..
