This paper discuss about ageing-like process of heating wood in completely dry conditions and the effects on creep properties for poplar wood (Populus alba). Creep tests have been performed in the radial direction, for heat treated and untreated samples over 10 hours. Beforehand some samples were heat treated at 150°C during a few days. Differences in creep phenomenon between new and aged samples are discussed with the help of graphical methods such as the approximated complex plane.
