Interaction of wood, water, and stresses during drying: A review
The anatomical structure of wood limits the rate of water movement through and out of wood. In addition the sensitivity of the structure to stresses which develop during drying, limits the drying rate and can cause various defects. In this paper the interactions between wood, water and heat are discussed from a basis of wood structure, wood-water relationships and the stresses which inevitably develop during drying. The effects of those stresses which manifest themselves in the form of drying defects are also discussed as well as the relationship between drying defects, machining and gluing problems.
