For many applications, such as the conservation of wooden cultural heritage, wooden construction, understanding and modelling the behaviour of ancient wood is important. During the 1950s, Kohara has shown that aged wood had not the same physical, mechanical and chemical properties as recent wood [2]; the models currently developed are based on non-aged wood and do not fit for our studies. Thus, the aim of our study, to both implement our model and work on a mimic of ancient wood, is to reproduce the properties of this " aged " material by accelerating aging process of recent wood.
