A method for generating finite element models of wood boards from X-ray computed tomography scans

A method is presented for reconstructing the geometry, pith, knots and local fibre orientations in timber boards, based on X-ray computed tomography scans. The deviations around were found by a new algorithm, image analysis. experimental data comprised scans, eigenfrequency measurements four-point bending tests of 20 Norway spruce boards. 3D 1D finite element models pure zone created, accounting exact board geometry reconstructed deviations. purely density based, mixed constitutive law compared. Model estimations showed high coefficient determination (R2) global modulus elasticity (MoE) (R2⩽0.93), MoE (R2⩽0.87), strength (R2⩽0.83), location initial failure. Constitutive laws most accurate results. In future, adapting logs could enable analyses boards before sawing.
