Thermal modification of wood was performed at 190(C and 200(C for 2 hours in industrial conditions. During the measurements, the moisture content of the modified and control samples was the same. The parameters compared included: modulus of elasticity, stress at proportionality limit, relative linear strain at proportionality limit and accumulated elastic energy. Thermal modification of ash wood at 190°C contributed to the deterioration of its mechanical parameters determined during compression in tangential direction; the deterioration was greater for wood tissue of higher moisture content. The values of mechanical parameters of thermally modified wood (except for elastic energy), determined in compression test in tangential direction, decrease with the its increasing moisture more than for the control wood. 2018 artículo científico 0717-3644 https://www.redalyc.org/articulo.oa?id=48557615010 https://www.redalyc.org/journal/485/48557615010/ https://www.redalyc.org/journal/485/48557615010/html/ https://www.redalyc.org/journal/485/48557615010/48557615010.epub https://www.redalyc.org/journal/485/48557615010/movil en http://www.redalyc.org/revista.oa?id=485 Maderas.
