Properties of UK-Grown Sitka Spruce: Extent and Sources of Variation. (2008)
Journal Article
Moore, J., Lyon, A. J., Ridley-Ellis, D., & Gardiner, B. A. (2008). Properties of UK-Grown Sitka Spruce: Extent and Sources of Variation. Timber Engineering,

Structural timber produced from Sitka spruce plantations in the UK typically achieves the requirements for the C16 strength class. However, very little is known about the variability of this plantation resource, or the factors that contribute to this...

Promoting the science and engineering of timber to children. (2008)
Journal Article
Ridley-Ellis, D. (2008). Promoting the science and engineering of timber to children. Timber Engineering,

The UK’s young people are generally very poorly informed about the opportunities that exist for them in wood science and timber engineering, and commonly perceive the sector to be old-fashioned, unrewarding, environmentally damaging, and requiring of...

Torsion tests on small and large-scale RHS with circular wall cut-outs (2007)
Presentation / Conference Contribution
Ridley-Ellis, D., Owen, J. S., & Davies, G. (2007, September). Torsion tests on small and large-scale RHS with circular wall cut-outs. Presented at 10th Intl Symp on Tubular Structures (ISTS), Madrid, Spain

The results of small and large-scale torsion tests on rectangular section tubes with circular wall perforations are presented and discussed. Perforations are shown to cause the torsional resistance to be re-duced by up to 60% and stiffness to be redu...

Torsional behaviour of rectangular hollow sections (2003)
Journal Article
Ridley-Ellis, D., Owen, J. S., & Davies, G. (2003). Torsional behaviour of rectangular hollow sections. Journal of Constructional Steel Research, 59, 641-663. https://doi.org/10.1016/S0143-974X%2802%2900060-3

The results of a series of full-scale torsion tests on rectangular hollow sections (RHS) are presented and discussed. The observed torque–twist behaviour is compared to that predicted by an extended version of Marshall’s simplified thick wall torsion...
