A model of the drying process end part of lumber were develope. It is shown that the uneven distribution of moisture along the length of the field material leads to the formation of the bending deformation of wood fibers, characteristic of the end face area assortment, which are the main cause of mechanical cracking of lumber. Experimental studies of the distribution of shrinkage, elastic and residual strain in the end face area of lumber were conducted. Modes of lumber drying solid hardwood warning mechanical cracking, wood moisture transport mechanism, hydraulic conductivity, moisture longitudinal current, and residual elastic deformation modes of drying were investigated.
