Conference Proceeding
Ridley-Ellis, D., Stapel, P. & Baño, V. (2015)
Strength grading of sawn timber in Europe - an explanation for engineers

Potential for estimating the age of instruments by characterisation of wood properties via acoustics.

Conference Proceeding
Ridley-Ellis, D., & Popescu, C. (2014)
Potential for estimating the age of instruments by characterisation of wood properties via acoustics
The performance of musical instruments is sensitive to several wood properties that are affected by aging. These wood properties also change with temperature and humidity in w...

Strength class of minor conifer species, as estimated from log acoustic measurements, small-clear data and knowledge of wood property variation

Conference Proceeding
Gil-Moreno, D., Ridley-Ellis, D., & McLean, J. P. (2014)
Strength class of minor conifer species, as estimated from log acoustic measurements, small-clear data and knowledge of wood property variation. In K. Schober (Ed.), COST Action FP1004 "Experimental Research with Timber", (214-218
It is well known that wood properties vary from species to species. Additionally, trees grow wood in response to their requirement to grow in a certain environment. Therefore,...

Stiffness changes during low temperature thermal treatment of Scots pine, assessed by acoustic NDT

Random acts of elasticity: MoE, G and EN408.

Conference Proceeding
Ridley-Ellis, D., Moore, J. & Khokhar, A. M. (2009)
Random acts of elasticity: MoE, G and EN408
The paper examines the variation in modulus of elasticity (MoE) and shear modulus (G) within sawn timber and the implications for testing timber in accordance with EN408:2003....
