 en Some Physical and Mechanical Properties of Daniellia Ogea check for this species in other resources Harms Green Timber Species


Throughout the antediluvian and up to date, humans keep understanding the nature of wood which has been used to meet some bunches of human’s demands such as in industry, in framing and in war. This paper presents some physical and mechanical properties of Daniellia ogea (Iya) green timber specie freshly felled from matured trees in forests around Ilorin Local Government, Kwara-State, Nigeria and cut into structural sizes within the Wood workshop of University of Ilorin premises according to BS EN 408: 2003. The moisture content and the density were the physical properties tested while the mechanical properties were the modulus of rupture and the local modulus of elasticity in bending strength, the apparent modulus of elasticity, the compressive strength perpendicular to grain then the compressive strength and tensile strength parallel to grain using the Universal Testing Machine of 300kN capacity of the food laboratory of the department of Agriculture of the University. Then the basic and grade stresses were determined and found to conform to the BS 5268 codes of practice. The results obtained post-tests for the moisture content and the density had respectively average values of 140.45% and 854.67 kg/m3.
