Wood, as a naturally grown material, is affected by growth inhomogeneities like branches.
Especially in solid timber or glulam beams, knots lead to a decrease in stiffness and …

Strength grading of timber boards is an important step before boards can be used as
lamellas in glued laminated timber. Grading is generally done visually or by machine …

Timber boards are numerically reconstructed in the full 3D space based on knot information
on the wood surface. The 3D model is then transformed into a full 3D-FEM model and …

Dans le cas du bois massif, les résistances en flexion et en traction peuvent être altérées par
la présence de défauts. Les nœuds et la distorsion du fil qui en découle, sont les causes de …

Abstract Samples of European beech (Fagus sylvatica) were used for this study. Logs of
these samples covered a scatter of mild-to-strong curvatures and the boards of these …

The strength of wooden boards is related to its natural defects and the ability of a stress
wave to propagate around them. Anisotropy, heterogeneity, and the strong moisture …

L'élaboration de composites structuraux BLC de Pin maritime de performances mécaniques
égales à celles du GL28c, représente un enjeu majeur pour une meilleure valorisation de la …

Structural wood-based materials such as glulam are widely used in larger spans for
construction purposes. Generally made of spruce, there are other species in use such as …

One of the important steps, before timber boards can be used as lamellas in glued laminated
timber and wood composites is strength grading. Grading is generally done visually (based …

Wood is a natural material with irregularities, in particular knots, that affect the global
stiffness and strength. The peculiarity of this material is the impossibility of eliminating all …
