ABSTRACT:
This invention provides an improved method for estimating the strength or stiffness of a piece of wood by measuring the longitudinal density profile of the wood. The density profile of the wood is determined by measuring the absorption or other modification of radiation at a sequence of local areas in the wood. The strength or stiffness estimation method identifies and quantifies those features in the wood density profile which describe two of the main wood factors that control overall wood strength or stiffness, i.e. the inherent (clear) wood strength or stiffness and the wood structural effect. The inherent wood strength or stiffness is mainly identified by the areas relatively constant density between knots, and the wood structural effect is mainly identified by the sharp density increases caused by knots. The strength or stiffness estimate for the wood combines these two factors.
