Investigation into the Physical and Mechanical Properties
Jul 05, 2017 An average of 50% reduction in the elastic modulus (Youngs modulus) of species found in Edo State was also observed as shown in Tables 8-11. This implies that stiffnesss are lower for species found in Edo State. In comparison to other species, locally and international, the Ekki wood gave the highest elastic modulus.
