Abstract

In Phase I of this study, the purpose was to compare mechanical and physical wood properties from current wood supplies to those from previous studies (Newlin and Wilson 1917, Markwardt and Wilson 1935, wood handbook 2010). The results indicate that minor changes have occurred in the hardwood species values from the previous two studies with a few exceptions. Differences, where they occurred, could be explained by the growth locations of each sample. Differences between pine values occurred for MOE and MOR, an increase in MOE and a decrease in MOR. The objective of Phase II was to correlate the non-destructive and destructive testing methods. The non-destructive test by longitudinal vibration wave can be used to predict the static modulus of elasticity since it is strongly correlated with the destructive static bending test for all the three methods used (A-Grader, FFT and Smart-Thumper).
