Abstract
Green gluing technology may have a large interest in wood industry. It allows energy saving so reducing costs. In order to fulfill requirements in relevant building codes and standards, these composite timbers have to present sufficient structural performance and shape stability. The drying step during the process of green gluing may lead to local strains and stresses development on the adhesive interface. This strains and stresses development could impact the shape stability of the product and induce joint failure. However, wood spatial microstructure may absorb these developments. It has to be noticed that, for an organic material like wood, the measurement of hygromechanical properties must be done without any interactions between the material and the measurement system. In order to process in this way, an optical measurement system such as the Digital Image Correlation can be used. Results give us the local behavior of the interface, during shrinkage and swelling of wood. The strains and stresses of the adhesive bond will be calculated from the measurement by the mean of an inverse method. Then, the structural performance of this new bonded material will be presented.
