Using the right Modulus of Elasticity to get the best grades out of softwood timber species in Great Britain (2016)
Presentation / Conference Contribution
Gil-Moreno, D., Ridley-Ellis, D., & McLean, P. (2016). Using the right Modulus of Elasticity to get the best grades out of softwood timber species in Great Britain. In WCTE 2016 World Conference on Timber Engineering e-book Full PapersThe correct characterisation of modulus of elasticity in bending is fundamental for timber grading, especially when that property limits the allocation to a strength class. The aim of this paper is to empirically determine the relationship between EN...
