1. Local variation in bending stiffness in structural timber of Norway spruce : for the purpose of strength grading
Abstract : Most strength grading machines on the European market use an averagemodulus of elasticity (MOE), estimated on a relatively large distance along awood member, as the indicating property (IP) to bending strength. Theaccuracy of such grading machines in terms of coefficient of determination israther low at R2 ≈ 0.5. READ MORE

2. Strength grading of structural timber and EWP laminations of Norway spruce : Development potentials
Abstract : Strength grading of structural timber is a process by which value is added to sawn products. It is to the greater part carried out using machine grading based on statistical relationships between so called indicating properties and bending strength. READ MORE

3. Strength grading of structural timber and EWP laminations of Norway spruce : Development potentials and industrial applications
Abstract : Machine strength grading of structural timber is a sawmill process by which considerable value is added to sawn products. The principle of such grading is that the strength of a timber member is predicted on the basis of a so called indicating property (IP) which, in general, represents an averaged value of the modulus of elasticity (MOE) measured over a board length of about one meter or more.
