“…Without any reconditioning, this is not only a measure for normal shrinkage due to drying below the fiber saturation point but also a measure for volume loss due to cell collapse. [29][30][31] Figure 4 shows the radial, tangential, and volumetric shrinkage of the boards dried in the three experiments. A one-way ANOVA showed that there are no significant differences between the three drying experiments regarding radial, tangential and volumetric shrinkage.…”

Worldwide, eucalyptus tree plantations have been established in appropriate climates because of fast growth and wood qualities suitable mainly for pulp. A potential exists of converting eucalyptus trees into lumber that may be of higher value than pulp. Conventional drying of lumber of Eucalyptus globulus is often difficult because of the occurrence of drying stresses, leading to collapse and checking. The special method of vacuum drying while heating the wood with high-frequency energy (75-77 mbar, 46-51 C) was used to obtain short drying times (5-13 days from green state to 10% final moisture content) and low crack amount.

The need for a drying stress indicator has previously been stated with some research in the past to this means. Given the recent successes in achieving this goal through monitoring shrinkage, the refinement and further understanding of the process was needed, specifically, the influence that penetration of the mount-foot had on the shrinkage data. Four different LVDTmounts were investigated in an attempt to acquire this information.The results indicated that the depth of penetration influenced the absolute value of shrinkage measured but did not influence determination of when peak stress occurred. The mounts mounted on the face of the board displayed the most stable and informative results.
