Analysis of Wood Cantilever Loaded at Free End

Jen Y. Liu, Douglas R. Rammer


A wood cantilever loaded at the free end was analyzed using the anisotropic elasticity theory. This report presents a two-dimensional numerical example of a Sitka spruce cantilever in the longitudinal- radial plane. When the grain slope is zero, i.e., the beam axis coincides with the longitudinal axis of wood, the stresses in the beam and the deflection of the beam are the same as those for an isotropic beam; when the grain slope is different from zero, the stresses and the deflection can increase significantly.
