Résumé

Mechanical characterization of veneers is a scientific obstacle for technical products made with them. These products as the LVL (Laminated Veneer Lumber) can have better properties than solid wood. In the objective to produce high-performance technical products, the mechanical characterization of veneers is necessary. To achieve this objective, an experimental protocol of 8 stages has been performed to characterize veneers of beech and poplar and quantify parameters such as the fiber orientation and components of the compliance matrix. This experimental protocol takes into account the manufacturing of specimens, the global and local density, the fiber orientations, the modulus of elasticity (MoE), and the shear modulus. The mechanical properties are found with the digital image correlation.
