ABSTRACT:
The invention relates to methods and apparatus for estimating stiffness or elasticity profiles across timber. This involves measuring a velocity of a plane compression wave propagating in the timber, determining density information relating to the timber and estimating an initial elasticity profile. A reiterative process is then conducted whereby a revised elasticity profile is determined using the density information and initial elasticity profile. The revised elasticity profile is then used to determine how the timber is utilised.
