Abstract: Researches on wood dynamic viscoelastic properties are focused in recent years. Dynamic viscoelastic properties are helpful for investigating wood rheology and provide scientific instructions for wood industry. This paper reviewed the effects mechanism of anatomy structure, chemical composition and moisture on wood dynamic viscoelastic properties. For the anatomy structure, the emphases were concerning the species, stress wood, heart wood and sap wood, juvenile wood and mature wood, grain direction and earlywood and latewood as well as microfibril angle. For the chemical composition, the emphases were concerning elastic fiber, viscoelastic matrix and extractives. The dependence of moisture to dynamical viscoelastic properties were summarized in this paper. The suggestions for further study to wood dynamic viscoelastic properties were put forward.
