Fig. 9From: Thermal softening properties of various wood species within an annual ringRelationships between the difference in the peak value of tanδ and the difference in the peak temperature of tanδ of EW and LW of various wood measured at 0.5 Hz. These differences are EW values minus LW. Filled circles, softwoods; open circles, hardwoods. a–e, Softwoods. f–i, Hardwoods. See Fig. 3 for more detailsBack to article page
