Eucalyptus fastigata Veneer Stiffness

By Doug Gaunt, May 2018.

Executive summary

UPT (ultrasonic propagation times) on its own is measuring both changes in density and changes in MoE, thus without an independent density measurement it is not possible to reliably determine veneer stiffness. If the UPT is combined with density, it is reasonable to assume the quality of the MoE prediction will be significantly improved.

As the UPT to stiffness relationship is affected by density, there will be different relationships between UPT and stiffness for different species. Thus the relationship obtained for these E. Fastigata veneers cannot be used outside the data set it was determined on.
