This communication deals with theoretical and experimental researches being carried out by the authors in order to model an actual wooden support, and its deformational behaviour, after a back frame has been applied by means of springs, in a Florentine restoration laboratory. Such a device is aimed to serve as a framing technique useful for conservation of one-sided painted boards of wooden artworks. The main outcome of such a research, still ongoing, is a calibrated mathematical and numerical model, which allows one to choose the most appropriate mechanical parameters for springs, according to expected environmental conditions, in order to achieve a balance between deformation control and stress control.
