Abstract

The current
methods for the determination of the strength properties for wood species for
grading purposes require extensive testing. Species independent grading might
be a solution for this problem, in particular for tropical hardwoods. The
strength reducing characteristics such as knots and slope of grain require two
groups for which species independent machine grading is possible. Theoretical
strength models are formulated and verified with data from a large database of
soft- and hardwoods.
