Viscoelastic Behavior of Wood in Changing Environments,
Abstract
Wood is an inherently heterogeneous material. Its behavior is hygroscopically unstable and anisotropically viscoelastic. Thus the full understanding of the responses of its viscoelastic behavior to the service environments is very important to the efficient and reliable design of wood structures. Furthermore, during the kiln drying of lumber and veneer, steaming logs for pelling, and hot pressing of wood composite boards, viscoelastic behavior plays a very important role. Normally, its strong sensitivity to moisture and temperature may induce some undesirable residual stresses. Such stresses are believed to have a significant influence on the development of drying effects in lumber and veneer and the dimensional stability of wood composite boards. However, in other materials, such as toughened glass, the induced residual stresses may be beneficial. (Author)
