Gil-Moreno, D., Ridley-Ellis, D., & Harte, A. M. (2021)
Test Machine Effect in the determination of modulus of elasticity for strength-graded timber. In WCTE 2021: World Conference on Timber Engineering Proceedings
This paper investigates if the relationship between the global and local moduli of elasticity (MoE), measured in bending tests, is affected by the test machines employed, and ...

Some awkward questions about density
Conference Proceeding
Ridley-Ellis, D., & Cramer, M. (2020)
Some awkward questions about density. In Timber 2020 Conference Proceedings. , (99-110
There are several different concepts of wood density, such as specific gravity, basic density, dry density, and oven dry density. These are often confusing, and sometimes poor...
Grading of British spruce cladding battens by ring width for density, fastener performance and fire
Conference Proceeding
Ridley-Ellis, D. (2019)
Grading of British spruce cladding battens by ring width for density, fastener performance and fire. In Proceedings of the 15th Annual Meeting of the Northern European Network for Wood Science and Engineering
The UK has a British Standard for external timber cladding, BS8605-1, in which support battens are defined as timber components of a section, grade, and durability, suitable f...
Influence of knot area indexes on tension strength of Sitka spruce
Conference Proceeding
Gil-Moreno, D., Ridley-Ellis, D., & Harte, A. M. (2019)
Influence of knot area indexes on tension strength of Sitka spruce. In Proceedings of the 15th Annual Meeting of the Northern European Network for Wood Science and Engineering
It is well known that knots can reduce the strength of timber, and the selection of “critical section” for testing to EN 408 and EN 384 is typically based on the size and posi...
Some thresholds for grading British grown spruce to optimised strength classes using longitudinal resonance
Conference Proceeding
Ridley-Ellis, D., Adams, S., & Lehneke, S. (2018)
Some thresholds for grading British grown spruce to optimised strength classes using longitudinal resonance
The main commercial species in the UK and Ireland is Sitka spruce (Picea sitchensis), which is graded in combination with a small amount of Norway spruce (P. abies). It is typ...
