| contents | Development of elastic strain and mechano-sorptive strain during conditioning of eucalyptus camaldulensis lumber in batch kiln Taian Chen Lianbai Gu Agrociencias MC Mechano camaldulensis Elastic strain sorptive strain Final conditioning of 25mm thick dried E. camaldulensis lumber was carried out in smallcapacity batch drying kiln in laboratory, and the elastic (EL) strain and mechano-sorptive (MS)strain was analyzed by slicing method. Mean moisture content(MC) of boards increases 2.5-3.0%,while surface MC increases from 9.8% to 14.2% and center MC always keeps at 12.3% or so.Difference of each slice oven-dried length, through the thickness of the board decreases with thegoing on of conditioning. Compressive EL strain in the surface decreases significantly during thefirst 9h of conditioning, and tensile EL strain in the center doesnt change significantly with thegoing on of conditioning. Compressive EL strain of sub-surface is greater than that of surfaceduring middle and final period of conditioning, so reverse stress gradient is formed. Casehardenedsurface is softened by moisture picking-up and then complementary shrinkage makes EL strainand MS strain decrease, but because of the effect of drying history, the change of MS strain lagsbehind that of MC. 2006 artículo científico 0717-3644 https://www.redalyc.org/articulo.oa?id=48580108 en http://www.redalyc.org/revista.oa?id=485 Maderas.
