Determination of Young's elastic modulus of plywood of Eucalyptus nitens (Deane & Maiden)

It was determined the Young`s elastic modulus (EMO) by three methods in a five-layer plywood from Eucalyptus nitens wood. The control method had the lowest variability (22,45 %). The lower standard error respect to control method, corresponds to method 2 with a coefficient of 0,566. While, the highe...
