3D lattice model for post-yield and fracture behaviour of timber. (2008)
Journal Article
Reichert, T., & Ridley-Ellis, D. (2008). 3D lattice model for post-yield and fracture behaviour of timber. Timber Engineering,

The paper describes the development of a bespoke Finite Element program to model timber with a three dimensional lattice of single spring elements. These springs mimic meso-scale timber behaviour, namely the crushing and separation of fibre bunches b... Read More about 3D lattice model for post-yield and fracture behaviour of timber..

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...

Determining the Shear Modulus of Sitka Spruce from Torsion Tests (2008)
Presentation / Conference Contribution
Khokhar, A., Zhang, H., Ridley-Ellis, D., & Moore, J. (2008). Determining the Shear Modulus of Sitka Spruce from Torsion Tests. In 10th World Conference on Timber Engineering 2008 (2137-2144)

This paper presents details of the experimental method, and preliminary results from, a series of torsion tests undertaken to evaluate the shear modulus of Sitka spruce (Picea sitchensis) timber. Direct torsion tests were used to determine the variat... Read More about Determining the Shear Modulus of Sitka Spruce from Torsion Tests.

Do people grow on trees? Guidance for employers in the Scottish forest and timber industries. (2008)
Report
Bond, S., Thomson, E., MacPherson, S., & Ridley-Ellis, D. (2008). Do people grow on trees? Guidance for employers in the Scottish forest and timber industries

The final report for the Forest Industries Recruitment and Retention (FIRRS) project. Forests and their products are hugely important to the economic and environmental sustainability of Scotland’s economy and influence many aspects of Scottish soc...

Whack-a-stick discovery. (2007)
Digital Artefact
Ridley-Ellis, D. (2007). Whack-a-stick discovery

This flash animation is a powerful simulation of the longitudinal vibration of a solid beam (the basic physics behind modern non-destructive methods of testing timber battens to measure stiffness and predict strength. You can see the effect of str... Read More about Whack-a-stick discovery..

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). Torsion tests on small and large-scale RHS with circular wall cut-outs.

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...

The Educational Needs of the Timber Industries – Report of an Online Survey by the Centre for Timber Engineering. (2006)
Report
Ridley-Ellis, D., & Nolte, S. (2006). The Educational Needs of the Timber Industries – Report of an Online Survey by the Centre for Timber Engineering

This survey was conducted by the Centre for Timber Engineering (CTE) in summer 2005 to investigate the educational needs and preferences of the timber industries. Both employers and employees were asked to define and articulate curriculum and skills...
