摘要：

This paper investigates the effects of steam pretreatment temperature (100 similar to 120 degrees C), test temperature (20 similar to 80 degrees C), and earlywood vessel belt on parameters associated with the bending creep properties of white oak (Quercus alba L.) wood. The Burger model, Five-parameter model, and Six-parameter model are used for short-term simulation and comparative analysis of the bending creep curve of steam-pretreated white oak wood, and creep fitting curves and viscoelastic parameters are obtained. The advantages and disadvantages of different viscoelastic mathematical models for fitting the bending creep curve of white oak are analyzed. The results indicate that the Six-parameter model is more consistent with the creep behavior of wood in simulating and predicting the creep behavior of wood than that of the Burger and Five-parameter model and can reflect the short-term deformation characteristics of wood.
