Results from the sensitivity study. The numbers represent the model ID of the analyses of Table 5; for simplicity, 15 cases among 50 were chosen, and the deflection [mm] versus time [days] is shown in the graphs, when a hypothetical decrease in RH corresponding to a 1% moisture content occurs. The graphs are sorted according to both paint layer rigidity (mainly of the ground layers) and emissivity. The latter increases from right to left, while the rigidity increases from bottom to top according to the values in Table 5. Case 10 represents the lowest rigidity and the lowest emissivity, while case 41 represents the highest rigidity and the highest emissivity. Moreover, case 1 represents the greatest paint layer emissivity and lowest paint layer rigidity; by contrast, case 50 represents the lowest emissivity and the greatest rigidity. The lower part of the figure shows the geometric reference model for each type of board that was associated with a different colour for each anatomical orientation. The values of the ordinates are proportional to the estimated deformation values to allow a better understanding of the deformation behaviour
