Some awkward questions about density (2020)
Presentation / Conference Contribution
Ridley-Ellis, D., & Cramer, M. (2020, September). Some awkward questions about density. Presented at Timber 2020, Online

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 poorly described in the literature, but they can be unambiguously defined and m... Read More about Some awkward questions about density.

Influence of knot area indexes on tension strength of Sitka spruce (2019)
Presentation / Conference Contribution
Gil-Moreno, D., Ridley-Ellis, D., & Harte, A. M. (2019, September). Influence of knot area indexes on tension strength of Sitka spruce. Presented at 15th Annual Meeting of the Northern European Network for Wood Science and Engineering, Lund, Sweden

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 position of knots. In Ireland, the visual strength grading Standard IS 127 spec... Read More about Influence of knot area indexes on tension strength of Sitka spruce.
