Wood drying is an essential process in the wood industry. During drying, the stress developed in the boards can produce several defaults such as deformations and cracks. The use of oscillating drying conditions should reduce the drying stresses in boards by activating the mechanosorptive creep. The best way to apply this concept remains an open question in the scientific community. In this paper, the effect of oscillating conditions on variations in moisture content across the board thickness was studied using an analytical model and a numerical code, TransPore. In addition, mechanical consequences of variations in moisture content produced by oscillations were studied by non-symmetrical drying (flying wood) and loaded drying (cantilever beam test). Beech wood, the second most commonly kiln-dried hardwood after oak in France, was chosen for this study owing to its elevated shrinkage coefficient, and hence its elevated risk of drying defaults.
