Failure in timber part II: The angle of shear through the cell wall during longitudinal compression stressing

Wood Science and Technology Aims and scope Submit manuscript

Summary

The angle at which the slip plane traverses the wall of cells subjected to longitudinal compression has been studied in detail and appears to be a function of the angle of the microfibrils in the middle layer of the secondary wall together with the ratio of the modulus of elasticity in the longitudinal and radial planes. These parameters can adequately explain the observed variations in slip plane angle that occurred between species, between early and late wood, and at different temperatures. Significant differences were absent in the comparison of radial and tangential walls, normal and compression wood, and samples at different moisture content.
