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...
