| contents | Creep parameters of spruce wood in high temperature environment Rastislav Lagaña Marian Babiak Alexander Krakovsky Agrociencias wood Creep spruce rheology high temperature treatment The paper presents partial results of an ongoing project dealing with thermal diffusion and mechanical behavior of spruce wood in high temperature environment (up to 180°C). The objective of this part of study was to obtain rheological properties of spruce wood which will be used in future modeling of wood performance in high temperatures. Oven dry samples (30 x 30 x 700 mm 3 ) underwent constant mechanical loading in bending parallel to grain ( σ max = 7.3 MPa, load span 600 mm) at three temperature levels, namely 120°C, 150°C and 180°C, respectively. De fl ection of the samples was measured using optical non-contact method. Four rheological parameters of Burger’s model, describing immediate elastic, delayed visco-elastic as well as plastic (permanent material change) behavior, were determined which show the strong in fl uence of the temperature on creep propagation. Experimental setup, results and further application in the modeling of high temperature treatment are discussed. 2008 artículo científico 0717-3644 https://www.redalyc.org/articulo.oa?id=48510102 es http://www.redalyc.org/revista.oa?id=485 Maderas.
