Summary
A hypothesis was proposed on the mechanism of the characteristic viscoelastic behavior of wood under moisture change. The hypothesis was based on the inference in which the characteristic behavior might be attributed to the looseness of the interface between the S1 and S2 layers in a cell wall. A mechanical model representing the behavior of a single cell wall on basis of the hypothesis and the results of simulation by the use of the mechanical model with the computer were shown in this report. The characteristics of the viscoelastic strain obtained from the simulation agreed well with those of published experimental results.
