ExaminateurIn order to improve strength grading methods for building timbers, the aim of this work is to design and to test a system which allows to evaluate, in a non destructive manner and in a reliable way, the longitudinal modulus of elasticity and the bending strength of sawn timbers. This goal also includes the possibility to detect and quantify the presence of wood defects. Several steps are required to reach this aim. For a better understanding, these steps are described both in the logical and chronological way. The first step reviews the classic t...
