Quantification of slip planes in the stem wood ofEucalyptus grandis
Source abstract
Abstract
Abstract The objective of this work was to analyze the natural occurrence of slip planes (SPs) inEucalyptus grandiswood fibers in terms of their characterization, distribution in the stem and associations with other wood characteristics. A 28-year-oldE. grandiswas studied, whose stems were sampled in the base-top direction. The longitudinal compressive stress regions (LCompSR, in the inner part of the stem) and longitudinal tensile stress region (LTensSR, in the outer parts of the stem) were separately considered. The following parameters were measured: microfibril angle (MFA), slip plane angle (SPA), number of SPs per millimeter (SP mm−1), slip plane index (SPI) and the relative abundance of SP in the fiber. The SPAs differ only slightly between LCompSR (76°) and LTensSR (77°). The base of the stem, which supports a larger mass, contains the most SPs and the number of SPs decreases from the base to the top. In the LCompSR, the SPI reduction was from 21 to 8%, and in the LTensSR, from 18 to 7%.
