Prediction of eucalyptus dunnii and pinus radiata timber stiffness using acoustics : a report for the RIRDC/Land and Water Australia/FWPRDC/MDBC Joint Venture Agroforestry Program / by Bill Joe ... [and others]
Increasing the recovery of high grade material is a primary objective of improving the profitability of growing trees for sawn products. Stiffness is the major basis of machine stress grading of sawn timber, and has a major influence on price. It is not a parameter, however, that is readily measured in logs or standing trees. Derivation of a surrogate indicator for stiffness would facilitate more effective planning and permit effective log sorting, while also providing a valuable tool for breeders and silviculturists working with standing trees. This study examined the relationship between stiffness and acoustic properties measured with a variety of stress wave timer tools, for both Eucalyptus dunnii and Pinus radiata
