    Description

    Flakeboards made with uniform densities throughout their thickness and different degrees of flake alignment were used to establish relationships between bending, tension, and compression values of modulus of elasticity or modulus of rupture (or stress to maximum load) and the variables of specific gravity and flake alignment. An equation using sonic velocity as an indicator of alignment was developed that describes the relations over a broad range with a high degree of confidence. Bending stiffness of boards having a density gradient were predicted within approximately ± 20% using the derived relationships.
