- INVESTIGATION OF OSCILLATING CLIMATES FOR WOOD DRYING USING THE FLYING WOOD TEST AND LOADED BEAMS: NEED FOR A NEW MECHANO-SORPTIVE MODEL Romain Rémond Mariella De La Cruz Daniel Aléon Patrick Perré Agrociencias beech mechano flying wood Drying stress sorptive model In this work, the effects of moisture content variations produced by oscillating drying conditions have been studied by means of non-symmetrical drying (flying wood) and loaded drying (3-point bending test). The oscillating conditions are intended to produce a mechano-sorptive creep that is able to reduce drying stresses. However, our experimental data seem to prove that the activation of the mechano-sorptive creep by oscillations of the moisture content is very limited. Besides, the simulations showed that noisy conditions due to the kiln regulation already activate the mechano-sorptive creep, even for non-oscillating conditions, and could confuse the results. Contrary to the experimental observations, the implementation of classical mechano-sorptive models in the drying simulation model is far too optimistic, which means that these models are not suitable when the material is submitted to numerous oscillations. 2013 artículo científico 0717-3644 https://www.redalyc.org/articulo.oa?id=48528861002 en http://www.redalyc.org/revista.oa?id=485 Maderas.
