The use of acoustic-based NDT to predict the wood properties of UK-grown Sitka spruce at different stages in the wood supply chain. (2009)
Presentation / Conference Contribution
Moore, J., Lyon, A. J., Searles, G. J., & Ridley-Ellis, D. (2009, May). The use of acoustic-based NDT to predict the wood properties of UK-grown Sitka spruce at different stages in the wood supply chain. Presented at 16th International Nondestructive Testing and Evaluation of Wood Symposium, Beijing, China

This paper is concerned with the extent to which portable stress-wave-based instruments can be used to segregate Sitka spruce trees and logs; in particular the relationship between acoustic velocity and the properties of sawn timber. Measurements wer... Read More about The use of acoustic-based NDT to predict the wood properties of UK-grown Sitka spruce at different stages in the wood supply chain..
