Modelling Knot Architecture in Radiata Pine Logs and Boards
A mathematical model was derived to describe knots in radiata pine logs and the boards quarter-sawn from these logs, based on the geometrical configuration and the growth features of the knots. Scenario simulations for the shape and the location of knots are presented, and the significance of studying knot architecture is discussed in the paper.
