The rubber tree (Hevea brasiliensis) is the main source of natural rubber production, with more than 14 million tonnes produced each year. Unfortunately, throughout their economic lifespan on the plantation (between 35 a...
-
Wood, commonly used in construction, stores carbon dioxide absorbed during its life cycle as carbon in the material. This study aims to use French wood species as a bio-sourced thermal insulation material with a preserve...
-
For in situ timber structures applications, heat and mass transfer are strongly dependent on temperature. This work focuses on a parametrical modeling to evaluate and quantify temperature effect at each stage. The model ...
-
The impact of variations of relative humidity, temperature and moisture content on the creep of notched beams of Douglas fir and white fir are investigated. Indoor static 4-points bending tests are followed by outdoor cr...

Le projet RUMO vise à améliorer la durabilité des résineux bois aux chargements Thermo-Visco-Hydro-Mécanosorptifs (TVHM). Ce matériau présente un fort potentiel en termes d’exploitation des ressources et d’emplois. Cepen...
-
Mechanosorption refers to the phenomena observed when wood is subjected simultaneously to mechanical loading and sorption resulting from changing hygrothermal conditions. A model based on the concept of hygro-locks has b...
-
The rings on the cross-section of the branch of a tree show the number of its years, and the greater or smaller width of these rings show which years were wetter and which drier. They also show the direction in which the...

The main biological function of reaction wood is to act as " muscle " for trees, enabling them to control their posture. The key property to achieve this function is the development of high mechanical stress during the f...
-
Wood is enjoying increasing popularity in the building sector. In order to fully exploit the potential of this material, particularly in two and three-dimensional structures, improved knowledge of the mechanical behavior...

Les composites bois/polymère sont généralement constitués d'un mélange de bois et de résines plastiques. D'autres matériaux lignocellulosiques peuvent également être utilisés tels que des coproduits agricoles comme la ba...
-
A 3D anisotropic visco-elastic numerical model using finite element method has been implemented in ANSYS using the user programmable feature. This model has been used to simulate the mechanical behavior of wooden panels ...
