ANISOTROPIC BEHAVIOUR OF NATURAL WOOD PALMYRA (BORASSUS AETHIOPUM MART) OF CHAD

The Palmyra (Borassus aethiopum Mart.) is a plant with great size none forked which produces lumber used in the domain of construction, housing and in textiles. Its anatomical structure brings up the naked eye in both directions of fiber orientation: one is parallel along the axis of growth of the trunk and the other is inclined relatively to this axis. It should be noted that in Chad we know very little about their scientific characteristics. This work concerns the determination of elastic constants of the wood of an individual aged of about 30 years
