### Dimensional Changes--Wood Deformation Produced by Solvents
#### 3.2.1 Results for Water Samples  
The water-immersed specimens, both the thin (12 mm) and the thick (27 mm) samples, curved either concavely or convexly. Where the values are negative as a result of the immersion, a change is produced that is in a direction lower than the initial value, resulting in deformation in the form of either bends or twists. Figure 9 identifies the changes that occurred after immersion in water in the samples with a section of 27 mm, as shown on the three horizontal axes. Pronounced deformation can be observed, compared to the original shape of the specimen. \begin{table}

Table 8: Deformations produced in the samples that were partially immersed in acetone. Figure 9: The deformations on the horizontal axis, shown on the three measuring lines, for the specimens with a thickness of 27 mm: (**a**) sample A2 (2P); (**b**) sample A1 (1P). The different deformation variations between the points were measured initially and after, as shown on the axis D-DY-C; D1-YD1-C1 is also highlighted in Figure 10a,b. The thin samples changed after being extracted from the water and strong curvatures were found, with a curvature radius of between 4 and 10 mm (Figures 11 and 12a) In their case, unlike with the thick samples, torsions (Figure 12b) were present with values of between 4 and 7 mm.
