Fig. 9From: Evaluation of increase in loss tangent from longitudinal vibration of wood log by considering apparent density difference between sapwood and heartwood caused by moisture contentComparison between measured H from sugi logs and calculated H. Difference in color denotes the classification of logs by corrected E/ρ in their moisture contents at FSP. The six lines are the same as Fig. 8. The logs whose sapwood moisture content is below 120% are excludedBack to article page
