The developed model of drying the face of the timber. It is shown that non-uniform field distribution along the length of the material humidity results in a bending deformation of wood fibers , characteristic only of end zone assortment , which is the main cause of mechanical cracking timber. Experimental study of the distribution of shrinkage, deformation and residual elastic strain in the face area of timber. Investigated modes lumber drying solid hardwood that prevent cracking of face .
