Vibration testing technique was used to determine dynamic modulus of elasticity of Acacia auriculaeformis, A. mangium, Bombax ceiba, Broussonetia papyrifera, Cocos nucifera, Dalbergia sissoo, Dendrocalamus strictus, Eucalyptus citriodora, E. tereticornis, Grevillea robusta, Hevea brasiliensis, Pinus spp, Santalum album, Shorea robusta, Simarouba glauca, Swietenia mahagoni and Tectona grandis in air-dry condition using microprocessor based elasto-sonic instrument. Static modulus of elasticity, modulus of rupture and fibre stress at limit of proportionality were evaluated by conventional test method. The results show statistically significant relationship of dynamic modulus of elasticity with static modulus of elasticity, modulus of rupture and fibre stress at limit of proportionality. Variation in dynamic modulus of elasticity was explained from the point of view of anatomical structure.
