This paper focuses on the viscoelasticity evaluation of the wood, based on simple relaxation test of Japanese cedar in its L, R directions. The viscoelastic parameters for these specimens were extracted based on regression analysis using results of compression test on several stroke rate. Adaptability of these parameters were verified by simulating the result of simple relaxation test. The characteristics of these woods depend on stroke rate. Using these parameters, it is possible to evaluate the stress relaxation of short term.
