In the future those could become interesting to be included in the industrial production process in sawmills as on-line quality control of timber. Before the possibilities have to be analysed to predict the strength by using the dynamic modulus of elasticity.
Defects reduce the elasticity severely.
The elasticity varies in a wide range. Defects had no clear influence on the variation of the elasticity. The occurrence of compression wood reduces the correlation between strength and elasticity. This tendency was equal for all samples and didn't depend on the type defect. 1998 August 17-20, Montreaux, Switzerland.
