Although computationally feasible, we do not attempt to account for all microstructural details and instead adopt a simplified analytical micromechanical model based on the Mori-Tanaka homogenization scheme to derive effective thermal conductivities of wood and effective diffusivities for the bound water present in the cell wall of wood and water vapor transported through lumens. As one particular example we consider a spruce wood as representative of softwood and most common in the production of glued laminated timber beams. 000021352 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000021352 653__ $$aSpruce, Thermal conductivity, Moisture diffusivity, Homogenization, Mori-Tanaka method. 000021352 7112_ $$aEngineering Mechanics 2017$$cSvratka, CZ$$d2017-05-15 / 2017-05-18$$gEM2017 000021352 720__ $$aKucíková, L.$$iŠejnoha, M.$$iSýkora, J.$$iVorel, J. 000021352 8560_ $$ffischerc@itam.cas.cz 000021352 8564_ $$s1011399$$uhttps://invenio.itam.cas.cz/record/21352/files/0550.pdf$$yOriginal version of the author's contribution in proceedings, page 550, section SOL. 000021352 962__ $$r21225 000021352 980__ $$aPAPER
