Dimensional changes and creep of spruce, and consequent model requirements

Wood Science and Technology Aims and scope Submit manuscript

Summary

The author gives numerical data resulting from detailed measurements on a common softwood,Picea abies; which can form the basis for the verification of new structural models of wood cell walls. Some suggestions are made for the interpretation of the data, including the development of internal stresses followed by relaxation, molecular destabilisation followed by physical aging during moisture changes, and differing forms of moisture bonding.
