Abstract Many pieces of fine art are made of wood that has been treated with coatings. Since wood is a very hygroscopic material, the moisture content strongly influences the deformation of wooden parts. Coatings often act as moisture barriers. There

A long-term experiment on the load bearing structure of two identical replica of a clavichord from 1807 is carried out. One clavichord is stored in a showcase with nearly constant exhibition room climate. The other one is stored in a climate chamber

A new hygro-mechanically coupled material model to simulate the structural behaviour of wooden objects below the fibre saturation area is introduced. A multi-F ick ian moisture transport model is coupled to a moisture-dependent, orthotropic, elasto-p

Hygro-mechanical phenomena induced by moisture loading of a historical wooden panel painting from the 16th century are investigated in this study. Due to swelling and shrinking strains resulting from an inappropriate and restraining support frame, da

The diffusion properties of walnut (Juglans regia L.) and cherry (Prunus avium L.) wood perpendicular to the grain are presented. The wet and dry cup tests were carried out in normal climate conditions. Simultaneously, inverse analyses by means of th

Wooden structures are quite complex with respect to their material properties as well as to their structural response and, therefore, need to be simulated appropriately by means of numerical methods. This review provides an overview of current simula

A comprehensive modelling of the transient hygro-mechanical behaviour of complex wooden structures by finite element method is targeted. New methods and material models for glutin-based bond lines are developed, since bond lines proved to have signif
