From: Hygromechanical behaviour of wooden panel paintings: classification of their deformation tendencies based on numerical modelling and experimental results

Fig. 7

Deformation tendency of wooden panel paintings examined by anatomical cut, depending on paint layer emissivity and ground layer rigidity. Each family of curves represents the 50 calculated models (Table 5) for each different cut of the table: this shows the enormous variability of values that can occur both within the same table and between different tables. It is emphasised that within the same table, variations in the stiffness of the paint layers and their emissivity alone can reduce the deformation tendency by up to an order of magnitude
