The shear strength and failure modes of timber joists obtained from the torsion test method. (2010)
Presentation / Conference Contribution
Khokhar, A. M., Zhang, H., & Ridley-Ellis, D. (2010). The shear strength and failure modes of timber joists obtained from the torsion test method. In A. Ceccotti (Ed.), 11th World Conference on Timber Engineering 2010 (WTCTE 2010) (3509-3516)

This paper presents details of the experimental method and test results from a series of torsion tests undertaken to evaluate the shear strength of timber joists. The failure modes and the correlation of shear strength and torsional shear modulus we...

Computational issues regarding lattice models for wood (2010)
Presentation / Conference Contribution
Reichert, T., & Ridley-Ellis, D. (2010). Computational issues regarding lattice models for wood. In A. Ceccotti (Ed.), 11th World Conference on Timber Engineering 2010 (WCTE 2010) (2127-2132)

This paper describes means to overcome some of the computational issues related to lattice models. The first is the use of a solution technique, different from a Newton-Raphson approach, called the Step-Size-Control (SSC) algorithm to handle strain-s...

The future of quality control for wood & wood products. (2010)
Presentation / Conference Contribution
(2010). The future of quality control for wood & wood products. In D. Ridley-Ellis, & J. Moore (Eds.), Proceedings of the final conference of COST Action E53

The principal aim of the COST Action E53 was to improve methods of quality control in processing round wood and timber to ensure that timber products and components meet the requirements of the users. The Action also promoted the improvement of spe... Read More about The future of quality control for wood & wood products..

Effects of genetics on the wood properties of Sitka spruce growing in the UK: bending strength and stiffness of structural timber. (2009)
Journal Article

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). Determination of shear strength of timber joists by torsion testing. In J. A. Santos (Ed.), Proceedings of COST E53 conference "Economic and Technical aspects of quality control for wood and wood produ

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). The use of acoustic-based NDT to predict the wood properties of UK-grown Sitka spruce at different stages in the wood supply chain. In H. Zhang, & X. Wang (Eds.), Proceedings of the 16th I

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..
